How to Join the Military: The Complete Enlistment Process

From your first recruiter meeting to shipping day: what to expect at every step in 2026.

Quick Answer

The military enlistment process takes 1–3 months and includes meeting a recruiter, passing the ASVAB, completing a medical exam at MEPS, choosing your job, entering the Delayed Entry Program, and shipping to basic training.

The Enlistment Timeline

Each step brings you closer to basic training. Here's what happens in order.

Recruiter Contact

You reach out online, by phone, or in person. The recruiter screens you for basic eligibility (age, education, citizenship) and answers your questions about branch options. Compare branches before committing. Read our choosing a branch guide.

Paperwork

You'll complete forms about your background, medical history, and legal record. Be honest. Anything you conceal can disqualify you later.

ASVAB

You take the Armed Services Vocational Aptitude Battery. Your score determines enlistment eligibility and which jobs you qualify for. Prepare with our free practice test.

MEPS

At the Military Entrance Processing Station, you undergo a full medical exam, meet with a career counselor to choose your job, and swear the oath of enlistment. Learn what to expect in our MEPS guide.

Job Selection

Your career counselor shows you jobs that match your ASVAB line scores. Never ship without a guaranteed MOS in your contract. See choosing your job for strategy.

DEP (Delayed Entry Program)

You enter a holding period of 1–12 months. You're not on active duty yet; you stay home and prepare.

Shipping Day

You report to your processing station and board transportation to basic training. Your military career officially begins.

What Disqualifies You?

Common barriers, and that waivers exist for some.

Felony convictions are almost always disqualifying. Some misdemeanors may be waivable depending on the branch and nature of the offense.

Certain medical conditions (such as asthma, ADHD, depression, or prior surgeries) can disqualify or require a medical waiver. Each case is reviewed individually.

Drug use (recent or repeated marijuana use, or any use of harder drugs) can bar enlistment. Honesty on your paperwork is critical.

Significant debt or financial instability can raise security concerns, especially for jobs requiring clearance.

Tattoos in certain locations (face, neck, hands) or with offensive content can disqualify. Policies vary by branch.

If you have a potential disqualifier, don't assume you're out. Waivers exist for many issues: medical, moral, and administrative. A recruiter can walk you through what's possible for your situation.
