Military conflict with Iran would trigger one of the most complex planning operations in U.S. history. But the real work happens long before the first shot is fired.

Behind any potential military operation lies a vast, intricate process of planning that’s far more complex than the execution itself. U.S. military planning isn’t one person making quick decisions—it’s a deeply layered system involving the entire national security apparatus.

Using Iran as a case study, this examination reveals how the U.S. government plans for contingencies involving sophisticated adversaries. This isn’t a declaration of intent to fight. It’s a fundamental responsibility of the armed forces: to be prepared.

The process is formal, structured, and guided by doctrine. It’s shaped by intelligence and constantly adapted to unique threats.

Where War Plans Begin

Military planning doesn’t start in the Pentagon. It’s a top-down process that begins with policy decisions at the highest levels of government. The objectives, constraints, and authorization for any military plan flow from civilian leadership.

This ensures that military force remains an instrument of national policy, not an end in itself.

The President and the National Security Council

The President, as Commander-in-Chief, has ultimate authority for directing military force. All military planning provides the President with credible, feasible options to protect and advance U.S. national interests.

The President’s principal forum for national security is the National Security Council. Established by the National Security Act of 1947, the NSC advises the President on integrating domestic, foreign, and military policies related to national security.

The council is chaired by the President. Its statutory members include the Vice President and the Secretaries of State, Defense, Treasury, and Energy. The Chairman of the Joint Chiefs of Staff serves as the military advisor, and the Director of National Intelligence is the intelligence advisor.

The NSC Committee System

To manage national security complexity, the NSC operates through a hierarchical committee system. This structure ensures that a potential crisis involving Iran gets examined from all angles—diplomatic, military, economic, and intelligence.

Interagency Policy Committees (IPCs): Chaired by senior NSC staff, these are the day-to-day workhorses. Assistant secretaries from relevant departments hash out policy details, like sanctions against Iran’s Islamic Revolutionary Guard Corps or diplomatic implications of military posture changes in the Persian Gulf.

Deputies Committee (DC): Chaired by the Deputy National Security Advisor, this committee of deputy secretaries reviews IPC work, resolves disputes between agencies, and ensures policy options are fully vetted.

Principals Committee (PC): Chaired by the National Security Advisor, this is the senior-most sub-cabinet forum. Cabinet-level officials conduct final review and consensus-building before presenting issues to the President.

The National Security Advisor manages the entire process. Their crucial role is acting as an honest broker, ensuring the President hears a full spectrum of views and that no single department’s perspective dominates decision-making.

When Crisis Moves Faster Than Committees

This structured system works well for long-term strategy but can be too slow for rapidly escalating conflicts. During a direct military exchange with Iran, a President would likely convene a small, ad-hoc group of core officials.

This concentrates decision-making power but risks excluding detailed regional and functional expertise developed at lower levels. It can lead to decisions with unforeseen consequences, like underestimating Iranian proxy reactions or impacts on global energy markets.

From Policy to Military Reality

Once the President and NSC establish a policy objective, the Department of Defense translates that political goal into military reality.

The Secretary of Defense, a civilian appointed by the President, heads the DoD and exercises authority over the entire department. This principle of civilian control is paramount. The SecDef issues strategic direction to the armed forces, as outlined in DoD Directive 5100.01.

The Chairman of the Joint Chiefs of Staff is the principal military advisor to the President, NSC, and SecDef. The Chairman is the nation’s highest-ranking military officer but doesn’t have operational command over forces.

Instead, the Chairman’s responsibilities lie in strategic planning, assessing global threats, evaluating military risks, and ensuring overall readiness of the joint force. The Joint Staff assists the CJCS in these duties. The J5 Directorate for Strategy, Plans, and Policy develops strategic recommendations for the Chairman.

The Joint Strategic Planning System

The CJCS uses the Joint Strategic Planning System (JSPS) to fulfill this advisory role. The JSPS is the formal process for assessing the strategic environment, analyzing threats, and developing military strategies to achieve national goals.

This process produces intelligence estimates and strategic plans that form the basis for military advice. An assessment of Iran’s missile capabilities or its support for proxy networks would be critical input into the JSPS.

Built-in Tension

This structure creates fundamental tension between political objectives and military planning. The NSC integrates all instruments of national power—diplomatic, informational, military, and economic. A decision related to Iran is never purely military.

Military planning doctrine requires clear, achievable, measurable objectives to structure coherent plans. A vague political goal like “send a message to Iran” is exceptionally difficult to translate into concrete military missions with defined end-states.

This necessitates continuous dialogue between civilian leaders and senior military officials. Their task is distilling broad policy guidance into specific military missions while ensuring resulting options truly serve strategic interests.

The Military’s Common Language

Once strategic guidance is issued, the U.S. military doesn’t improvise. It turns to a comprehensive body of established principles called joint doctrine. This provides the intellectual foundation and common language for planning military operations.

Joint Doctrine Fundamentals

Joint doctrine is the authoritative body of fundamental principles guiding employment of U.S. military forces toward common objectives. It’s not rigid rules but a guide to action, representing “distilled insights and wisdom gained from employing the military instrument of national power” in past operations.

The keystone publication for military planning is Joint Publication 5-0 (JP 5-0), Joint Planning. This document establishes the core framework for how the military approaches planning.

It defines joint planning as the deliberate process of determining “how (the ways) to use military capabilities (the means) in time and space to achieve objectives (the ends), while considering the associated risks.”

This “ends-ways-means-risk” model is the fundamental logic underpinning all military plans. JP 5-0 guidance is authoritative across the entire Department of Defense.

When Services Work Together

Each military service—Army, Navy, Air Force, Marine Corps, and Space Force—has specific planning processes tailored to its domain. But joint doctrine takes precedence whenever two or more services operate together.

In any conceivable contingency involving a state actor like Iran, operations would be inherently joint, requiring seamless integration of air power, naval forces, special operations, cyber capabilities, and space-based assets.

The Joint Planning Process (JPP) outlined in JP 5-0 serves as the master blueprint, ensuring unity of effort.

Core Planning Principles

Modern joint doctrine has evolved significantly from older, rigid planning models. It now emphasizes flexibility, adaptability, and deep understanding of the operational environment. Core principles guiding contemporary planning against complex adversaries like Iran include:

Commander-Led and Design-Focused: Modern planning isn’t merely a staff exercise. Doctrine places the commander at the center, personally responsible for driving efforts to understand the environment and define the problem before detailed planning begins.

This initial phase, “operational design,” is a highly cognitive activity involving critical thinking, questioning assumptions, and fostering dialogue among planners, intelligence experts, and other stakeholders.

For a challenge like Iran, a commander can’t simply ask for a plan to “attack.” They must first lead deep analysis of Iran’s strategic culture, political objectives, military doctrine, economic vulnerabilities, and societal dynamics to accurately frame the problem the military is being asked to solve.

Resource and Risk-Informed: Joint planning is explicitly “resource-informed and time-constrained.” Planners don’t develop options in a fantasy world of unlimited forces, funding, or time. They work within constraints of what’s realistically available.

Planning involves continuous risk assessment. Planners must identify and articulate risks associated with any proposed course of action—including potential costs in military casualties, civilian harm, damage to alliances, and geopolitical blowback—and propose measures to mitigate those risks.

Adaptive and Flexible: The modern operational environment is complex, dynamic, and uncertain. Military plans aren’t rigid, unchangeable scripts. They’re adaptable frameworks for action.

Planners build in flexibility through “branches” and “sequels.” Branches are pre-planned contingencies accounting for anticipated changes (e.g., “If the adversary does A, we execute Branch Plan 1”). Sequels are subsequent plans following successful completion of current operations.

For an Iran scenario, a campaign plan would contain numerous branches to account for potential escalatory actions, like Hezbollah’s full-scale entry into conflict or Iran’s attempt to close the Strait of Hormuz.

Why Doctrine Changed

This evolution in joint doctrine away from rigid, phased models directly responds to the nature of modern adversaries like Iran. Traditional, linear planning frameworks worked well for conventional, state-on-state warfare with clear combat phases.

But a state like Iran operates across what its strategists call a “competition continuum,” employing hybrid conventional and unconventional methods—including proxy warfare, cyberattacks, and information operations—that blur lines between peace and war.

This reality demanded doctrinal shift. The emphasis on “operational design” and “adaptive planning” acknowledges that conflict with Iran wouldn’t be simple or predictable but a complex, multi-domain struggle where strategic context could shift rapidly.

Commander’s Intent

The doctrinal emphasis on “commander’s intent” is critical for countering asymmetric adversaries. Asymmetric warfare creates chaos and exploits seams in a more powerful opponent’s decision-making cycle. Highly detailed plans can quickly become obsolete.

By ensuring every subordinate leader understands the commander’s overall purpose and desired end-state, doctrine empowers them to exercise “disciplined initiative.” They can adapt actions to fluid reality and seize opportunities or mitigate threats without waiting for new orders.

In conflict with Iran, a naval commander in the Persian Gulf facing a sudden swarm attack by IRGC fast boats, or a cyber operator detecting unexpected network intrusion, must be empowered to act decisively within the commander’s intent.

The Regional Commander: U.S. Central Command

After strategic guidance is established and doctrinal framework understood, planning focus shifts from Washington to regional commanders responsible for specific parts of the world.

For any contingency involving Iran, the primary military headquarters responsible for planning and potential execution is U.S. Central Command (CENTCOM).

The Unified Command Structure

The modern U.S. military command structure is a direct product of the landmark Goldwater-Nichols Department of Defense Reorganization Act of 1986. This legislation fixed severe inter-service coordination problems witnessed in previous operations.

It dramatically streamlined the operational chain of command, which now runs directly from the President to the Secretary of Defense, then to commanders of Unified Combatant Commands (CCMDs).

Service chiefs (Chief of Staff of the Army, Chief of Naval Operations) are responsible for organizing, training, and equipping forces, but they’re not in the operational chain for warfighting. This reform ensures a single, joint commander is responsible and accountable for all military assets and operations within their assigned area or function.

Geographic and Functional Commands

The Department of Defense maintains 11 CCMDs divided into two categories:

Geographic Combatant Commands (GCCs): Seven GCCs each assigned specific geographic “Areas of Responsibility” (AOR). These include U.S. European Command (EUCOM), U.S. Indo-Pacific Command (INDOPACOM), and U.S. Central Command (CENTCOM).

Functional Combatant Commands (FCCs): Four FCCs each responsible for specific missions on a global basis. These include U.S. Special Operations Command (SOCOM), U.S. Strategic Command (STRATCOM), U.S. Transportation Command (TRANSCOM), and U.S. Cyber Command (CYBERCOM).

While a plan for conflict with Iran would be developed and led by CENTCOM, execution would require extensive support from functional commands. SOCOM would provide special operations forces, STRATCOM would handle strategic deterrence and global strike capabilities, TRANSCOM would manage massive logistical deployment efforts, and CYBERCOM would lead cyberspace operations.

CENTCOM: In the Center of the Storm

U.S. Central Command was formally established January 1, 1983, evolving from the earlier Rapid Deployment Joint Task Force (RDJTF). The RDJTF was created in 1980 in direct response to growing Middle East instability, specifically the Iran hostage crisis and Soviet invasion of Afghanistan.

CENTCOM’s AOR covers the “central” region of the globe—a vast, volatile area of 21 nations stretching from Egypt in the west to Kazakhstan in the east, encompassing the Middle East, the Levant, and parts of Central and South Asia.

Geographically and strategically, Iran lies at the very heart of this AOR. The command is headquartered at MacDill Air Force Base in Tampa, Florida, with a forward headquarters at Al Udeid Air Base in Qatar.

CENTCOM’s official mission is to “direct and enable military operations and activities with Allies and Partners to increase regional security and stability in support of enduring U.S. interests.”

In its 2023 Theater Strategy document, CENTCOM explicitly lists “Deter Iran” as one of its three primary strategic priorities, alongside countering violent extremist organizations and competing strategically with China and Russia.

This makes clear that planning for and managing the Iranian threat is a central, defining task for the command.

CENTCOM’s Component Commands

CENTCOM operates through service component commands, which would execute their respective portions of any contingency plan:

• U.S. Army Central (ARCENT): Manages land-based operations
• U.S. Air Forces Central (AFCENT): Provides air and space power
• U.S. Naval Forces Central Command (NAVCENT): Leads naval operations, including maritime security
• U.S. Marine Corps Forces Central Command (MARCENT): Provides expeditionary crisis response forces
• Special Operations Command Central (SOCCENT): Conducts special operations and counterterrorism missions

Strategic Evolution

CENTCOM commanders regularly testify before Congress and make public statements that serve as strategic messaging. These statements signal U.S. resolve and readiness to adversaries like Iran.

In June 2025 testimony, CENTCOM Commander Gen. Michael Kurilla confirmed that the command has prepared a “wide range of options” for the President to prevent Iran from obtaining a nuclear weapon and that CENTCOM is prepared to respond with “overwhelming force” if directed.

A key element of CENTCOM’s current strategy is significant evolution in its approach to regional security. The command’s official strategy documents describe transformation from being a “security guarantor” to a “security integrator.”

This is a subtle but profound shift. For decades, the United States was the unquestioned, primary military power in the Persian Gulf, essentially guaranteeing the security of its Arab partners.

The new strategy reflects dual reality: broader U.S. strategic rebalance toward competition with China and Russia, and the fact that regional partners, particularly Israel and Gulf Cooperation Council states, have developed highly advanced military capabilities.

CENTCOM’s role is evolving to “integrate” these partners into a broader, networked security architecture. This means a conflict plan for Iran is no longer solely about what U.S. forces will do in isolation.

It’s about how CENTCOM will coordinate with and enable partner actions, deconflict overlapping operations, share intelligence, and build collective defense. This approach creates a more formidable and layered deterrent against Iran but introduces immense complexity and political sensitivity into planning.

Command Location Strategy

Another deliberate strategic choice is locating CENTCOM’s main headquarters in Tampa, Florida, thousands of miles from its AOR. While maintaining a forward headquarters in Qatar is essential for day-to-day engagement, placing the primary command element within the continental United States provides significant strategic advantages.

It ensures security and resilience of the command element, insulating it from potential Iranian first strikes. It also facilitates closer and more rapid coordination with national leadership in Washington and with U.S.-based functional commands like CYBERCOM and STRATCOM.

This geographic separation is a key component of ensuring command and control survivability in modern, high-intensity conflict.

The Planning Engine: Joint Planning Process in Action

With strategic guidance from Washington and a regional commander tasked with the mission, the abstract concept of “planning” becomes concrete, methodical, and highly structured activity.

CENTCOM, like all joint commands, uses the Joint Planning Process (JPP) to translate broad strategic objectives into detailed, executable military plans. The JPP is the “orderly, analytical process” providing commanders and staffs with a logical sequence of steps.

The Seven-Step Process

The JPP consists of seven distinct steps, often grouped into four major functions. While presented sequentially, these steps are iterative, and in time-constrained crises, several may be conducted simultaneously.

Planning Initiation

A formal planning effort begins when higher authority—typically the President, via the Secretary of Defense—issues strategic guidance or directive to a Combatant Commander. This initiation officially triggers the JPP.

Iran Example: Following intelligence reports that Iran is making credible preparations to deploy naval mines in the Strait of Hormuz, the White House convenes emergency NSC session. The consensus is that this action poses unacceptable threat to global commerce and regional stability.

The President directs the Secretary of Defense to develop military options. The SecDef issues a planning directive to CENTCOM to initiate contingency planning ensuring freedom of navigation.

Mission Analysis

Mission analysis is arguably the most important and intellectually demanding step in the entire process. The planning team deconstructs strategic guidance to gain deep, shared understanding of the problem.

The staff analyzes the operational environment, identifies all specified tasks (explicitly stated in directive) and implied tasks (must be done to accomplish specified tasks), determines constraints (things they must do) and restraints (things they cannot do), and assesses available resources.

Iran Example: Upon receiving the planning directive, CENTCOM’s joint planning group begins mission analysis. The J2 (Intelligence) directorate provides detailed assessment of the operational environment.

This includes analysis of Iran’s naval capabilities in the Strait, focusing on IRGC Navy’s swarm boats, anti-ship cruise missiles, and naval mines. It also assesses disposition and intent of Iranian proxies like Hezbollah and the Houthis, who might retaliate regionally.

The J5 (Plans) directorate analyzes political and economic impacts of potential Strait closure. The staff identifies critical facts and develops planning assumptions.

From this comprehensive analysis, the team crafts a proposed mission statement: “On order, U.S. Central Command conducts maritime security operations in the Strait of Hormuz to ensure freedom of navigation and deter further Iranian aggression in the region.”

Course of Action Development

With a clear mission statement, the staff develops several distinct COAs to accomplish it. A good COA is suitable (accomplishes the mission), feasible (can be done with available resources), acceptable (anticipated costs are proportional to objective), distinguishable (significantly different from other COAs), and complete (answers who, what, where, when, why, and how).

Iran Example: The CENTCOM planning team develops three distinct COAs:

COA 1 (Deterrent Posture): Limited, non-kinetic option focused on strategic messaging. Involves deploying additional aircraft carrier strike group to Arabian Sea, increasing intelligence, surveillance, and reconnaissance flights over the Gulf, and launching coordinated public information campaign to signal U.S. resolve and readiness.

COA 2 (Defensive Escort): More active option involving U.S. naval warships and allied vessels escorting convoys of commercial tankers through the Strait. Rules of engagement would authorize defensive fire against any Iranian assets posing imminent threat to the convoy.

COA 3 (Offensive Counter-Maritime): Most aggressive option involving preemptive, limited strikes against specific IRGC naval bases, coastal missile batteries, and command-and-control facilities identified during mission analysis as essential to Iran’s ability to close the Strait.

COA Analysis and Wargaming

Each developed COA is rigorously tested through analysis and wargaming. Wargaming is a disciplined, iterative process where planning staff, often divided into “Blue Team” (friendly forces) and “Red Team” (adversary forces), thinks through each COA step by step.

It’s mental simulation of action, reaction, and counteraction between sides. This critical step helps planners identify potential strengths, weaknesses, risks, and unforeseen consequences of each option.

Iran Example: For COA 3, the wargame explores a sequence of events. The Blue Team simulates U.S. airstrikes on IRGC facilities. The Red Team, thinking like Iranian commanders, determines their most likely reaction.

Would they launch ballistic missiles at U.S. bases in Qatar and Bahrain? Would they order Hezbollah to fire rockets at Israel? Would cyber actors attempt to disrupt the U.S. financial sector?

The Blue Team then devises counteraction. This process continues through several turns, allowing planners to assess escalation potential and identify decision points where the commander might need to choose a different path.

COA Comparison

Following the wargame, staff conducts formal comparison of COAs. They evaluate each option against established criteria, typically including factors like mission accomplishment, speed of execution, risk to U.S. forces, potential for collateral damage, and likelihood of controlling escalation.

The staff presents the commander with analysis summary and often recommends one COA over others.

Iran Example: The planning staff presents its comparison to the CENTCOM commander. COA 1 is judged lowest risk but has low probability of deterring determined Iran. COA 3 is assessed as having highest probability of quickly reopening the Strait but carries unacceptably high risk of triggering wider regional war.

COA 2 is identified as most balanced option, directly addressing the mission of ensuring free passage while managing escalation by maintaining defensive posture. The staff recommends COA 2.

COA Approval

The Combatant Commander reviews staff analysis and comparison, applies their own experience and judgment, and selects the COA they believe will best accomplish the mission within acceptable risk levels.

This decision isn’t final—the commander then briefs their recommended COA up the chain to the Secretary of Defense and President for final approval.

Iran Example: The CENTCOM commander concurs with staff assessment and selects COA 2. They prepare detailed briefing for the Secretary of Defense and Chairman of the Joint Chiefs.

In the briefing, they present all three COAs and wargame results, explain their rationale for selecting COA 2, but also present COA 3 as viable branch plan that could be executed if the defensive escort mission fails to deter Iranian attacks.

The President, after consulting with the NSC, gives final approval for COA 2.

Plan or Order Development

Once a COA is approved by the President, the staff’s final task is transforming it into fully detailed operational plan (OPLAN) or, if execution is imminent, operational order (OPORD).

This document is comprehensive blueprint for the operation. It contains all necessary details for subordinate units to execute the mission, including precise task organization, specific missions for each component command, concept of operations, detailed logistics and sustainment plans, intelligence requirements, and specific rules of engagement governing use of force.

Iran Example: The approved COA 2 is developed into detailed OPORD. U.S. Naval Forces Central (NAVCENT) is designated as lead component for the escort mission. U.S. Air Forces Central (AFCENT) is tasked with providing persistent air cover and ISR over the Strait.

U.S. Special Operations Command Central (SOCCENT) is placed on alert for potential personnel recovery missions. U.S. Cyber Command (CYBERCOM) is directed to intensify defensive cyber operations to protect military and shipping networks from Iranian interference and prepare offensive cyber options for execution if authorized.

The OPORD is then disseminated to all participating commands, and forces begin final preparations for execution.

Planning Against Iran’s Unique Military Doctrine

The Joint Planning Process provides universal framework, but any plan’s substance is dictated by the specific adversary it’s designed to counter. Planning for potential conflict with Iran is uniquely complex because Iran isn’t a conventional, peer competitor.

Its military doctrine, shaped by decades of revolution, war, and sanctions, relies heavily on asymmetric capabilities designed to exploit perceived vulnerabilities of a technologically superior power like the United States.

U.S. planners at CENTCOM must develop options accounting for multi-domain, multi-front conflict that would likely extend far beyond Iran’s borders.

Military Capability Comparison

The Dual Military Challenge

A fundamental complexity in planning for an Iran scenario is its unique dual-military structure. Iran maintains two separate and parallel armed forces: the Artesh, which is the conventional state military, and the Islamic Revolutionary Guard Corps (IRGC), which is an ideological force charged with defending the 1979 revolution itself.

The Artesh resembles a traditional military, with army, navy, and air force responsible for defending Iran’s territorial integrity against external invasion. However, due to decades of sanctions, its equipment is largely obsolete.

The IRGC is far more than a military force. It’s a deeply entrenched political, economic, and ideological institution wielding immense power within the Iranian system. Crucially, the IRGC controls Iran’s most potent military assets: its vast ballistic missile arsenal and the elite Quds Force, which manages its network of foreign proxies.

This duality is often cited as structural weakness for Iran due to institutional rivalries and redundancies. However, from a defensive standpoint, it creates powerful strategic resilience that complicates U.S. planning.

An attacker is forced to make difficult choices. Degrading the conventional Artesh might have little impact on the regime’s ability to retaliate using IRGC’s asymmetric tools. Conversely, targeting the IRGC directly constitutes highly escalatory attack on the regime’s core.

This forces U.S. planners to essentially prepare for two different types of adversaries within a single country, enhancing regime survivability, which is Iran’s ultimate strategic objective.

Forward Defense: War Fought by Proxies

Iran’s grand strategy is built on a doctrine of “forward defense.” Lacking ability to project conventional power, Iran seeks to confront adversaries far from its own borders, using its extensive network of regional proxies and partners.

This “Axis of Resistance” isn’t a formal alliance but a web of state and non-state actors receiving funding, training, and advanced weaponry from the IRGC’s Quds Force.

This network includes highly capable groups like Hezbollah in Lebanon, which possesses an arsenal of some 150,000 rockets and missiles; the Houthi movement in Yemen, which has used Iranian-supplied missiles and drones to attack shipping in the Red Sea; and various powerful Shia militias in Iraq and Syria.

The planning implication is profound: conflict with Iran wouldn’t be confined to its borders—it would instantly become regional war. U.S. planners can’t focus solely on targets inside Iran.

They must simultaneously develop plans to defend allies and U.S. forces across the Middle East from coordinated, multi-front attacks. This could involve countering Houthi anti-ship missiles in the Bab el-Mandeb strait, defending U.S. bases in Iraq and Syria from militia drone attacks, and supporting Israel’s defense against massive Hezbollah rocket barrages.

This creates immense challenges of geographic scope, resource allocation, and escalation management.

The Missile and Drone Threat

Recognizing its inability to compete with the U.S. Air Force, Iran has strategically invested in ballistic missile and unmanned aerial vehicle programs as its primary means of long-range strike and strategic deterrence.

Iran possesses the largest and most diverse missile arsenal in the Middle East, with thousands of short- and medium-range missiles capable of striking targets across the region, including U.S. military bases and Israeli population centers.

While many older systems lack precision, Iran is steadily improving accuracy of newer solid-fueled missiles.

In parallel, its drone program has matured rapidly, producing a range of UAVs for surveillance and attack, most notably long-range “suicide drones” like the Shahed-136, which have been used effectively in regional conflicts.

For U.S. planners, this threat dictates two primary lines of effort. First is establishing robust, multi-layered integrated air and missile defense (IAMD) architecture to protect U.S. forces, bases, and key allied infrastructure.

This involves a network of ground-based systems like Patriot and THAAD, sea-based Aegis ballistic missile defense ships, and fighter aircraft.

Second is the offensive mission of “counter-strike,” which involves the difficult intelligence and targeting challenge of finding and destroying Iran’s assets before they can be launched. This is complicated by Iran’s use of mobile launchers and extensive network of hardened, underground storage facilities designed to ensure missile force survivability.

War in Cyberspace

Iran views cyberspace as a critical asymmetric battlefield—a low-cost way to strike back at conventionally superior United States. It employs a mix of government organizations, such as the IRGC and Ministry of Intelligence and Security, and a host of deniable proxies and front groups to conduct cyber operations.

Iranian cyber tactics have evolved from simple website defacements to sophisticated and dangerous operations, including espionage against defense and technology companies, disruptive Distributed Denial of Service attacks, and destructive “wiper” malware designed to destroy data and cripple networks.

Iran has also become adept at information warfare, using fake news sites, AI-generated content, and social media trolls to spread propaganda and sow discord in target countries.

Any military plan for Iran must have significant cyber component. U.S. Cyber Command works closely with CENTCOM to plan both defensive and offensive cyber operations.

Defensive measures involve “hardening” U.S. military and critical infrastructure networks against intrusion. Offensively, the U.S. pursues a strategy of “persistent engagement” and “defending forward,” which means actively operating in adversary cyberspace to disrupt malicious activity before it reaches U.S. networks.

Planners must also integrate strategy to counter the inevitable wave of Iranian disinformation that would accompany any kinetic conflict.

Controlling the Strait of Hormuz

The Strait of Hormuz is a narrow waterway separating Iran from the Arabian Peninsula. It’s the world’s single most important energy chokepoint. Nearly a quarter of total global oil consumption and a third of the world’s liquefied natural gas passes through this strait daily.

Iran’s naval doctrine, particularly that of the IRGC Navy, is explicitly designed to hold this vital artery at risk. Lacking a large blue-water navy, the IRGC relies on asymmetric tactics to threaten shipping.

This includes potential for “swarming” attacks by hundreds of small, fast, heavily armed attack boats; deployment of large naval mine inventory; and use of shore-based anti-ship cruise and ballistic missiles to target any vessel in the narrow waterway.

Because Strait closure, even for short periods, could send shockwaves through the global economy, ensuring freedom of navigation is paramount mission for U.S. planners.

This specific contingency receives immense planning attention. A plan to keep the Strait open would require robust naval presence led by NAVCENT, specialized tactics to counter swarm threats, advanced mine-clearing capabilities, and dominant air power from AFCENT to destroy coastal missile batteries and provide protective cover for commercial shipping.

Iran’s Evolving Strategy

Iran’s military doctrine isn’t static. It’s a learning and evolving system. Analysis shows gradual shift from purely asymmetric posture to more complex “hybrid” model that seeks to blend unconventional strengths with more advanced conventional capabilities, often acquired with technological help from Russia and China.

This evolution complicates U.S. planning, which must now prepare for an adversary that can fight both like a guerrilla force and, in limited but growing ways, like a conventional military.

The greatest challenge for U.S. planners isn’t risk of direct military defeat but danger of being drawn into the very conflict Iran’s strategy is designed to create: protracted, multi-front, low-intensity war that erodes American political will and economic resources.

Iran knows it can’t win conventional force-on-force conflict. Its entire doctrine is based on “attrition warfare that raises an opponent’s risks and costs.”

By activating proxies across the region, threatening global economic chokepoints, and engaging in deniable cyberattacks, Iran’s strategy aims to turn what the U.S. wants—quick, decisive military operation—into politically unsustainable quagmire.

The ultimate objective for U.S. military planners isn’t simply winning individual engagements, but designing campaigns that can achieve core objectives rapidly and create conditions to terminate conflict on favorable terms, before this strategy of strategic attrition can succeed.

The Complexity of Modern Military Planning

This examination of how the U.S. military plans for potential conflict with Iran reveals the extraordinary complexity of modern military planning. It’s not generals moving pieces on a map—it’s a sophisticated, multi-layered process involving hundreds of experts across multiple agencies and commands.

The process begins with presidential guidance filtered through the National Security Council’s committee system. It flows through the Pentagon’s civilian leadership to the Joint Chiefs of Staff, then to regional commanders like those at CENTCOM.

Each level adds expertise, constraints, and considerations. The result is military options that reflect not just tactical realities but political objectives, alliance considerations, economic impacts, and long-term strategic consequences.

The Iranian case study illustrates why this planning is so complex. Iran isn’t a conventional adversary that fights by familiar rules. Its strategy deliberately blurs lines between war and peace, combines state and non-state actors, and spans multiple domains from cyber to proxy warfare.

Planning against such an adversary requires scenarios that account for regional escalation, proxy activation, economic warfare, and information operations. It demands integration of diplomatic, economic, and military tools. It requires consideration of how allies and partners would respond and what role they would play.

The seven-step Joint Planning Process provides structure, but the substance requires deep understanding of Iranian culture, strategy, capabilities, and intentions. It requires wargaming scenarios that might seem like science fiction but reflect Iran’s documented doctrine and capabilities.

Most importantly, it requires constant adaptation. Iran’s strategy evolves. Its capabilities grow. Regional dynamics shift. Military plans must be living documents, constantly updated as intelligence assessments change and new technologies emerge.

This planning process represents one of the most sophisticated analytical enterprises in government. It combines military expertise with intelligence analysis, diplomatic considerations, economic modeling, and strategic thinking.

The goal isn’t to start wars but to prevent them through credible deterrence and, if deterrence fails, to provide national leadership with viable options that can achieve political objectives while minimizing costs and risks.

The complexity of this planning reflects the complexity of modern warfare itself. In an era when conflict can span domains from cyberspace to outer space, when non-state actors wield capabilities once reserved for major powers, and when economic and information warfare can be as decisive as kinetic operations, military planning must be equally sophisticated.

The Iran case study shows this system at work. It reveals how abstract strategic guidance gets translated into concrete military options. It demonstrates how doctrine provides framework while intelligence shapes substance. It illustrates how military planning must account for political constraints and strategic consequences.

Most fundamentally, it shows how military force remains an instrument of policy, not an end in itself. Every step of the planning process is designed to ensure that if military force is used, it serves broader national interests and strategic objectives.

This is planning for the possibility of war conducted in the hope that credible preparation will make war unnecessary.
