Height and Weight Requirements

The military enforces height and weight standards to ensure service members can perform physical tasks effectively and maintain good health. These standards vary by branch and are based on the correlation between body composition and physical performance.

Height Requirements:

Minimum and maximum height requirements by branch:

• Army: Between 58-80 inches (4’10” to 6’8″)
• Navy: Between 57-80 inches (4’9″ to 6’8″)
• Air Force: Between 58-80 inches (4’10” to 6’8″)

• Coast Guard: Between 58-80 inches (4’10” to 6’8″)

Height waivers may be available but are typically granted only for exceptional candidates.

Weight Requirements:

Weight standards are based on height and age, with each branch publishing detailed tables. Generally, they follow these guidelines:

1. Screening Weight: Initial assessment based on height-weight tables
2. Body Composition Assessment: If exceeding screening weight, body fat percentage is measured

Maximum body fat percentage allowances vary by branch and gender:

• Army: 20-26% for men, 30-36% for women (varies by age)
• Navy: 22-26% for men, 33-36% for women (varies by age)
• Air Force: 18-26% for men, 26-32% for women (varies by age)
• Marines: 18-20% for men, 26-28% for women (varies by age)

If you’re currently outside the standards, it’s recommended to achieve and maintain the required weight for at least 2-3 months before applying to ensure stability.

Moral Character and Background Checks

The military holds service members to high moral standards, as they represent the United States and may have access to sensitive information or powerful weapons systems. Extensive background checks help ensure recruits meet these standards.

Background Investigation Process:

All applicants undergo thorough background checks that include:

• Criminal record search: National and local
• Credit history review: Assessing financial responsibility
• Interview with references: Character assessment
• Employment verification: Work history and performance
• Education verification: Confirmation of claimed credentials
• Security clearance investigation: For positions requiring clearance
• Drug testing: Both at application and randomly throughout service

Criminal History Considerations:

Not all criminal offenses automatically disqualify candidates, but many can seriously impact eligibility:

Potentially Disqualifying Offenses:

• Felony convictions
• Domestic violence convictions (permanently disqualifying under the Lautenberg Amendment)
• Multiple misdemeanors, especially for violence, theft, or drug offenses
• Drug distribution charges
• Any offense indicating poor judgment, lack of respect for authority, or violent tendencies

Minor Offenses:

Minor traffic violations or non-violent juvenile offenses may not be disqualifying but must be disclosed.

Moral Waivers:

Moral waivers may be granted for certain offenses based on:

• Nature and severity of the offense
• Age at time of offense
• Time elapsed since the offense
• Evidence of rehabilitation
• Overall qualifications of the applicant
• Military recruiting needs

Waiver approval becomes progressively more difficult with more serious offenses and typically requires:

• Detailed explanation of circumstances
• Character references
• Evidence of positive life changes
• Command-level review and approval

Financial History Considerations:

Financial responsibility is considered an indicator of personal discipline and trustworthiness, particularly for positions requiring security clearances:

• Excessive debt or poor debt management may be concerning
• Bankruptcies don’t automatically disqualify but require explanation
• Pattern of financial irresponsibility could affect eligibility
• Significant unexplained financial assets may trigger additional scrutiny

Honesty Throughout the Process:

The single most important aspect of moral character assessment is honesty:

• Disclose all required information, even if potentially disqualifying
• Lying or omitting information is itself grounds for disqualification
• If discovered later, fraudulent enlistment could result in discharge or prosecution
• Recruiters can provide guidance on addressing potential issues

Financial History Considerations

Your financial history plays a significant role in military eligibility, particularly for positions requiring security clearances. Financial responsibility is viewed as an indicator of personal discipline, judgment, and vulnerability to compromise.

Why Financial History Matters:

The military evaluates financial history for several reasons:

• Security risk assessment: Financial problems could make personnel vulnerable to bribery or coercion
• Judgment and responsibility: Financial management reflects decision-making abilities
• Stress management: Financial issues can impact focus and performance
• Reliability indicator: Consistent bill payment history suggests dependability

Key Financial Factors Examined:

Background investigations typically review:

Credit Reports:

• Payment history
• Debt-to-income ratio
• Outstanding collections
• Credit utilization
• Public records (bankruptcies, foreclosures, liens)

Specific Financial Concerns:

• Excessive debt: Especially high debt-to-income ratios
• Delinquent accounts: Especially federal debts including student loans
• Bankruptcies: Chapter 7 or 13 filings within recent years
• Tax liens or evasion: Unpaid taxes are particularly concerning
• Gambling debts: May indicate judgment issues
• Unexplained affluence: Assets inconsistent with known income sources

Potential Disqualifiers:

While each case is evaluated individually, these financial issues raise serious concerns:

• Currently delinquent on federal debts
• Ongoing pattern of financial irresponsibility
• Unwillingness to resolve financial problems
• Significant unexplained income
• Evidence of illegal financial activities
• Gambling addiction with associated debts

Preparing Your Financial History:

To address potential financial concerns:

1. Review your credit reports from all three major bureaus
2. Resolve outstanding collections when possible
3. Create payment plans for debts you cannot immediately pay
4. Document all efforts to resolve financial issues
5. Prepare explanations for negative items on your credit report
6. Obtain proof of payments for recently resolved accounts

Security Clearance Considerations:

For positions requiring security clearances, financial scrutiny increases significantly:

• More detailed financial disclosure is required
• Foreign financial interests receive additional scrutiny
• Regular reinvestigations include updated financial reviews
• Continued financial responsibility is expected throughout service

Financial issues don’t automatically disqualify candidates if they:

• Show a good-faith effort to resolve problems
• Have a reasonable plan for debt management
• Can explain the circumstances that led to financial difficulties
• Demonstrate improved financial habits

Family Considerations

Family circumstances affect both eligibility for military service and the type of service you can perform. The military evaluates family situations to ensure recruits can fulfill their service obligations while maintaining family stability.

Dependents and Single Parents:

The military places restrictions on enlistment for individuals with dependents, particularly single parents:

Active Duty Enlistment:

• Single applicants without children: No restrictions
• Married applicants with children: Generally allowed to enlist with appropriate family care plans
• Single parents: May face significant restrictions or require custody waivers

Each branch has specific policies:

• Army: Single parents must relinquish custody of children to enlist (custody change must be permanent and court-approved)
• Navy: Similar to Army, requires custody transfer for single parents
• Air Force: May grant waivers for single parents with established family care plans
• Marines: Most restrictive toward single parents, generally requiring custody transfer
• Coast Guard: Reviews single parent cases individually, often requiring waivers

Reserve/National Guard Enlistment:

Policies for Reserve and National Guard components are typically more accommodating for single parents, who may be able to enlist with appropriate family care plans without transferring custody.

Family Care Plans:

All service members with dependents must establish a Family Care Plan, which includes:

• Short-term caregiver: Someone locally available for emergencies
• Long-term caregiver: Designated for deployments or extended training
• Financial arrangements: Ensuring dependents’ needs will be met
• Legal documentation: Powers of attorney and potential guardianship agreements
• Logistical plans: Transportation, medical care, education arrangements

Marriage to Foreign Nationals:

Being married to a non-U.S. citizen can impact:

• Security clearance eligibility
• Overseas assignment options
• Special reporting requirements

These marriages don’t prevent enlistment but may limit career options, particularly in sensitive fields.

Dependent-Related Waivers:

Waivers related to family situations may be considered based on:

• Military occupational specialty needs
• Applicant’s qualifications
• Stability of family care arrangements
• Branch-specific policies and current recruitment goals

Considerations for Military Families:

Potential recruits with families should consider:

• Frequent relocations (typically every 2-4 years)
• Potential for extended separations during deployments
• Availability of military family support services
• Educational impacts on children
• Spouse employment challenges
• Access to healthcare through TRICARE

The military offers numerous family support programs, but service requires significant family flexibility and resilience.

ASVAB Testing

The Armed Services Vocational Aptitude Battery (ASVAB) is a critical standardized test that determines both your eligibility to join the military and the career fields available to you. Understanding the test structure and preparing effectively can significantly impact your military career options.

Test Structure and Scoring:

The ASVAB consists of nine subtests:

1. General Science (GS): Physical, biological, and earth sciences
2. Arithmetic Reasoning (AR): Math word problems
3. Word Knowledge (WK): Vocabulary through synonyms
4. Paragraph Comprehension (PC): Reading comprehension
5. Mathematics Knowledge (MK): High school mathematics principles
6. Electronics Information (EI): Electrical principles and electronic systems
7. Auto Information (AI): Automobile technology and repair
8. Shop Information (SI): Tool knowledge and mechanical principles
9. Mechanical Comprehension (MC): Mechanical and physical principles

Key Scores:

• Armed Forces Qualification Test (AFQT) Score: Derived from four subtests (AR, MK, WK, PC) and expressed as a percentile
• Line Scores: Various combinations of subtests used to determine qualification for specific military occupations

Minimum AFQT Score Requirements:

• Army: 31 (high school diploma), 50 (GED)
• Navy: 35 (high school diploma), 50 (GED)
• Air Force: 36 (high school diploma), 65 (GED)
• Marines: 32 (high school diploma), 50 (GED)
• Coast Guard: 40 (high school diploma), 50 (GED)
• Space Force: Similar to Air Force requirements

Test Formats:

The ASVAB is offered in two formats:

1. Computer Adaptive Test (CAT-ASVAB): Taken at Military Entrance Processing Stations (MEPS)
   • Approximately 1.5 hours
   • Questions adapt based on performance
2. Paper and Pencil (P&P-ASVAB): Administered at schools and satellite Military Entrance Test (MET) sites
   • Approximately 3 hours
   • Fixed question set

Career Qualification:

Your ASVAB scores determine which military jobs (MOSs, ratings, or AFSCs) you qualify for:

• Higher-scoring candidates have more career options
• Technical fields typically require higher line scores
• Each military occupation has specific score requirements
• Scores remain valid for 2 years

Preparation Strategies:

Effective ASVAB preparation can significantly improve your score:

1. Understand the test format: Familiarize yourself with question types and time constraints
2. Identify weak areas: Take practice tests to determine which sections need most improvement
3. Study resources:
   • Official ASVAB study guide
   • Online practice tests
   • ASVAB prep apps
   • Library resources
   • Commercial study guides
4. Focused practice: Concentrate on areas that heavily impact both AFQT and desired career field scores
5. Test-taking strategies:
   • Manage time effectively
   • Answer every question (no penalty for guessing)
   • Read all questions carefully
   • Eliminate obviously wrong answers

Retaking the Test:

If you’re dissatisfied with your score:

• Must wait 30 days to retake after first attempt
• Must wait 6 months after second attempt
• Military accepts the most recent score, not the highest

For career planning purposes, aim for an AFQT score above the minimum requirements, as higher scores provide more career options and potential enlistment incentives.

Disqualifying Factors

Understanding potential disqualifying factors can help you assess your eligibility and prepare for possible waiver requests. While some disqualifications are absolute, many can be reviewed through the waiver process.

Medical Disqualifications:

Certain medical conditions typically prevent military service:

• Chronic or unstable conditions requiring ongoing treatment
• Conditions affecting physical performance: Severe asthma, uncontrolled diabetes, heart conditions
• Mental health disorders: Bipolar disorder, recent major depression, schizophrenia
• Neurological conditions: Epilepsy, multiple sclerosis, history of traumatic brain injury
• Sensory impairments: Significant hearing loss, severe vision problems not correctable
• Orthopedic issues: Major joint reconstructions, back problems with mobility limitations
• Recent surgeries: Usually temporarily disqualifying until fully healed
• Certain medication dependencies: Particularly psychiatric medications, insulin

Legal Disqualifications:

Legal issues that may prevent enlistment include:

• Felony convictions: Especially violent crimes, sex offenses, drug distribution
• Multiple misdemeanor convictions: Pattern of criminal behavior
• Domestic violence convictions: Automatically disqualifying under the Lautenberg Amendment
• Drug-related offenses: Particularly distribution or multiple possession charges
• Gang affiliation: Past or present
• Pending criminal charges or probation: Must be resolved before enlistment
• Court restraining orders: Active orders may be disqualifying

Substance-Related Issues:

Drug and alcohol history is carefully evaluated:

• Current drug use: All branches prohibit current drug use
• Past hard drug use: Heroin, cocaine, methamphetamine, LSD, etc.
• Extensive marijuana use: Policies vary by branch but frequent use raises concerns
• Drug distribution: Selling drugs is a major red flag
• Multiple alcohol-related incidents: DUIs, public intoxication
• Drug or alcohol addiction: History of dependency or treatment
• Failed drug tests during application process: Often permanently disqualifying

Moral and Administrative Issues:

Other potential disqualifiers include:

• Excessive debt: Particularly unpaid federal debts
• Dishonorable discharge from previous military service
• Significant tattoos: Face, neck, or hand tattoos; gang-related or offensive content
• Dependent care issues: Single parent custody situations
• Security concerns: Foreign preference, concerning foreign contacts
• Previous military separation: Particularly for disciplinary reasons

• History of body modification: Significant non-traditional modifications
• Uncorrected dental issues: Severe orthodontic problems
• Excessive body piercings: Branch-specific standards apply

Remember that disqualification standards evolve with military needs, medical advancements, and policy changes. Always disclose all potential issues honestly—concealment itself is grounds for rejection or later administrative action.

Waivers: When Exceptions Can Be Made

The military waiver process allows individuals who don’t meet standard eligibility criteria to still be considered for service. While waivers aren’t guaranteed, understanding the process can help you present the strongest possible case.

Types of Waivers:

Various categories of waivers exist for different eligibility issues:

1. Medical Waivers: For conditions that don’t significantly impact military performance
2. Moral Waivers: For minor criminal offenses or character issues
3. Age Waivers: For candidates slightly outside age requirements
4. Dependent Waivers: For family situation exceptions
5. Education Waivers: For educational background variances
6. Prior Service Waivers: For previous military service issues
7. Drug Use Waivers: For past substance use (policies vary widely by branch)
8. Administrative Waivers: For miscellaneous policy exceptions

Waiver Approval Factors:

Several factors influence whether a waiver will be approved:

• Military needs: Recruiting goals and personnel shortages
• Candidate qualifications: High ASVAB scores, education, or desirable skills
• Time elapsed: Greater distance from the disqualifying issue
• Severity and pattern: Isolated incident vs. repeated problems
• Mitigation efforts: Steps taken to address or improve the situation
• Level of risk: Potential impact on military readiness and unit cohesion
• Branch policies: Standards vary significantly between services

The more desirable your overall package (high test scores, education, skills), the better your chances for waiver approval.

Waiver Process:

The typical waiver process involves:

1. Initial disclosure: Complete honesty about disqualifying issues
2. Documentation gathering: Collecting relevant records and supporting evidence
3. Personal statement: Explaining circumstances and personal growth
4. Character references: Letters supporting your character and reliability
5. Recruiter submission: Your recruiter packages and submits the waiver
6. Chain of command review: Waivers move up through increasing authority levels
7. Determination: Approval, request for more information, or denial

The process typically takes 2-8 weeks but can extend longer for complex cases.

Waiver Likelihood by Branch:

The likelihood of waiver approval varies significantly by military branch:

• Army: Generally most flexible with waivers, particularly during high recruitment periods
• Navy: Moderately accommodating, especially for technical positions
• Air Force: Most selective with waivers, maintains stricter standards
• Marines: Very selective with moral waivers, somewhat more flexible with minor medical issues
• Coast Guard: Highly selective due to small size and high competition
• Space Force: Extremely selective, similar to Air Force standards

Preparing a Strong Waiver Case:

To maximize waiver chances:

1. Be completely honest: Dishonesty is itself disqualifying
2. Gather comprehensive documentation: Medical records, court documents, etc.
3. Demonstrate rehabilitation/improvement: Evidence of positive change
4. Obtain strong character references: From respected community members
5. Highlight valuable skills: Special abilities, education, or experiences
6. Work closely with your recruiter: They know the current waiver climate
7. Consider branch selection strategically: Some branches may be more receptive to your specific waiver

Remember that each case is evaluated individually, and similar cases may have different outcomes depending on timing, branch needs, and other factors.

Preparing to Meet Requirements

If you’re interested in military service but don’t currently meet all requirements, proactive preparation can significantly improve your chances of qualification. This section outlines strategies to address common eligibility obstacles.

Physical Fitness Preparation:

Starting from a base fitness level, build gradually toward military standards:

1. Establish a baseline: Assess your current push-up, sit-up, and run capabilities
2. Create a progressive training plan:
   • Begin with modified exercises if necessary
   • Gradually increase intensity and volume
   • Include both strength and cardiovascular training
   • Add interval training to improve run times
3. Follow branch-specific training:
   • Focus on exercises tested by your target branch
   • Practice the actual testing protocols
   • Target the specific standards for your age/gender category
4. Consider professional guidance:
   • Personal trainers familiar with military requirements
   • Former military fitness instructors
   • Military prep programs

Allow 3-6 months of consistent training to see significant improvements.

Educational Preparation:

If you lack required educational credentials:

1. Complete high school or equivalent:
   • Finish traditional high school if possible
   • Pursue GED preparation and testing
   • Consider adult high school completion programs
2. Improve ASVAB scores:
   • Use official study guides and practice tests
   • Address knowledge gaps in core subjects
   • Consider ASVAB prep courses
   • Focus on weak areas identified in practice tests
3. Pursue college credits:
   • Even 15 college credits can classify GED holders as Tier 1
   • Community college courses are cost-effective options
   • Consider online education opportunities

Medical Issue Remediation:

For potentially correctable medical conditions:

1. Consult healthcare providers:
   • Ask specifically about military qualification implications
   • Request documentation of resolved conditions
   • Follow treatment plans completely
2. Common correctable issues:
   • Vision: LASIK/PRK surgery (must wait 6-12 months after)
   • Weight: Healthy, gradual weight loss programs
   • Allergies: Allergy treatments and documentation
   • Orthopedic: Physical therapy and rehabilitation
   • Asthma: Pulmonary function testing if symptom-free
3. Maintain medical documentation:
   • Keep organized records of all treatments
   • Request written statements regarding resolution
   • Document stability periods for managed conditions

Legal Issue Remediation:

For addressing legal obstacles:

1. Resolve pending matters:
   • Complete court obligations
   • Finish probation/parole periods
   • Pay all fines and restitution
2. Document rehabilitation:
   • Community service participation
   • Character reference letters
   • Educational achievements
   • Stable employment history
   • Clean record since incident
3. Expungement or record sealing:
   • Investigate eligibility for expungement
   • Understand this doesn’t remove military obligation to disclose
   • Obtain certified court documents showing disposition

Financial Preparation:

To address financial concerns:

1. Obtain credit reports from all three major bureaus
2. Create debt management plans:
   • Establish payment arrangements for delinquent accounts
   • Prioritize federal debt resolution
   • Document all payment arrangements
3. Reduce debt-to-income ratio where possible
4. Correct credit report errors through formal dispute processes
5. Save documentation of all financial remediation efforts

Timeline Expectations:

Realistic preparation timelines to consider:

• Physical fitness: 3-6 months for significant improvement
• Weight standards: Allow 6-12 months for substantial changes
• ASVAB improvement: 1-3 months of focused study
• GED completion: 2-6 months depending on starting knowledge
• Medical waivers: 2-8 weeks processing after documentation
• Legal issues: Varies widely by issue; some require multiple years of demonstrated stability
• Financial improvements: 6-12 months to show payment history improvements

Remember that recruiting standards fluctuate with military needs and congressional authorizations. What might be disqualifying today could be waiverable in the future, so maintaining contact with recruiters even while preparing can provide valuable insights into changing standards.

Frequently Asked Questions

General Eligibility Questions

Q: Can I join the military with dual citizenship? A: Yes, dual citizens can join the military, but you may be required to renounce your foreign citizenship for certain positions requiring security clearances. Each case is evaluated individually, and factors like which countries are involved play a significant role in the determination.

Q: Does being on prescription medications automatically disqualify me? A: Not necessarily. The military evaluates medications based on:

• The condition being treated
• Stability without medication
• Potential consequences if medication is unavailable
• Operational limitations caused by the medication

Medications for certain conditions (particularly psychiatric conditions, diabetes requiring insulin, or severe allergies requiring epinephrine) are more likely to be disqualifying.

Q: Can I join if I’ve had mental health treatment in the past? A: Past mental health treatment doesn’t automatically disqualify you. The military considers:

• The specific diagnosis
• Severity and duration of symptoms
• Time since treatment ended
• Current functioning without medication
• Risk of recurrence in military environments

Generally, you must be stable without medication for a period (typically 24-36 months) for conditions like depression or anxiety.

Physical Standards Questions

Q: Can I join the military if I’m overweight? A: You must meet weight and body fat standards before shipping to basic training. If you’re currently over these limits, work with a recruiter on a weight loss plan. Once you meet the standards, you can proceed with enlistment. The military doesn’t offer “weight loss programs” during the recruitment process.

Q: What if I can’t do enough push-ups or run fast enough yet? A: Physical fitness standards must be met during basic training, not necessarily at application. However, preparation is essential—if you’re significantly below standards, focus on a progressive training program before enlisting to avoid training injuries or potential discharge.

Q: Can I join with tattoos? A: Current tattoo policies vary by branch but have generally become more lenient. Most branches now allow:

• Tattoos on most body areas except face, neck above crew collar, and hands (with some exceptions for ring tattoos)
• No offensive content, gang symbols, or extremist imagery

Each branch has specific size and location limitations, so check current policies with recruiters.

Process Questions

Q: How long does the application process take? A: From initial contact with a recruiter to shipping for basic training typically takes 3-9 months, depending on:

• Medical clearance complexity
• Security clearance requirements
• Waiver processing (if needed)
• Job availability and training slots
• DEP (Delayed Entry Program) duration

Q: Can I choose my job/career field? A: Job selection opportunities vary by branch:

• Army: Offers guaranteed job contracts for qualified applicants
• Navy: Guarantees a career field but not always a specific job
• Air Force: Typically requires listing multiple job preferences
• Marines: Generally guarantees only a job field, not specific jobs
• Coast Guard: Limited job guarantees based on service needs
• Space Force: Extremely limited direct entry opportunities

Higher ASVAB scores generally provide more job options across all branches.

Q: Can I back out after talking to a recruiter? A: Yes. Until you take the oath of enlistment at MEPS, you have no military obligation. Even in the Delayed Entry Program, while there are administrative consequences for withdrawal, there are no legal penalties for deciding not to proceed.

Special Circumstances

Q: Can I join with a GED instead of a high school diploma? A: Yes, but with limitations:

• Branches limit the percentage of GED holders they accept
• GED holders typically need higher ASVAB scores (usually 50+)
• Some branches require additional college credits for GED holders
• During high recruitment periods, these restrictions may be relaxed

Q: I’m a single parent. Can I join the military? A: Single parents face additional requirements:

• For active duty, most branches require custody transfer for enlistment
• For reserves/guard, waivers with family care plans may be possible
• Officer programs may have more flexible policies
• Prior service single parents may have different consideration

Q: Does being LGBTQ+ affect my eligibility to serve? A: No. Since the repeal of “Don’t Ask, Don’t Tell” and changes in transgender service policies, sexual orientation and gender identity are not disqualifying factors for military service. Transgender individuals can serve in their self-identified gender once transition is recognized by the Department of Defense.

Medical Questions

Q: Can I join with a history of asthma? A: Possibly. The current standard generally allows enlistment if you:

• Have been symptom-free without medication for at least 5 years
• Can pass a pulmonary function test
• Had childhood asthma that resolved before age 13

Severe or exercise-induced asthma may still be disqualifying.

Q: Can I join after having LASIK or PRK eye surgery? A: Yes, after a stabilization period. The military accepts candidates who have had LASIK or PRK surgery, but you must:

• Wait 6-12 months after surgery (varies by branch)
• Have stable vision with no complications
• Provide complete surgical documentation
• Meet vision standards for your desired job/branch

Q: Are there height minimums and maximums? A: Yes, though requirements have become more flexible. Generally:

• Minimum: Approximately 58-60 inches (4’10”-5’0″)
• Maximum: Approximately 80 inches (6’8″)

Requirements vary by branch and some specialized positions (like pilots) have more specific height requirements based on operational equipment constraints.

Remember that policies change regularly, and individual circumstances vary widely. For the most accurate information about your specific situation, consult with recruiters from multiple branches to understand all your options.
