Pre-Military Guide

A comprehensive, plain-language guide for anyone considering military service. Whether you're in high school, college, or making a career change, this section covers everything you need to know before you raise your right hand.

The Enlistment Process — Step by Step

  1. Research — Learn about branches, jobs, benefits, and lifestyle using the guides below and official websites.
  2. Contact a recruiter — Visit or call. Ask questions. Bring a trusted person. Talking to a recruiter does not commit you to anything.
  3. Take the ASVAB — At a school, Mobile Examining Team Site, or at MEPS. Study first — your scores determine which jobs are available to you.
  4. Go to MEPS — Medical exam, ASVAB (if not already taken), job selection, and swearing in. Typically 1–2 days.
  5. Enter the Delayed Entry Program (DEP) — Wait for your ship date (days to months). Stay in shape and stay out of trouble.
  6. Ship to basic training — Return to MEPS on your ship date, sign your final contract, swear in, and ship out.
  7. Complete basic training — 7.5 to 13 weeks depending on your branch.
  8. Attend job training — AIT, "A" School, Tech School, or MOS school. Duration varies by job.
  9. Report to your first duty station — Begin your military career.

Citizenship & Residency

  • Must be a U.S. citizen or permanent resident (green card holder)
  • Permanent residents can enlist but cannot hold jobs requiring a security clearance until they become citizens

Education

  • High school diploma: Strongly preferred — over 90% of recruits have one

  • Home school diploma: Accepted by most branches if it meets certain criteria
  • College credits: Can qualify you for advanced rank at entry (E-2 or E-3)

Criminal History

  • Felony convictions are generally disqualifying (some waivers possible)
  • Multiple misdemeanors may be disqualifying
  • Drug-related offenses are taken very seriously
  • DUI/DWI may require a waiver
  • Full disclosure is required. The military will find out — lying is grounds for disqualification or discharge for fraudulent enlistment

Drug Testing

  • Urinalysis at MEPS — a positive test means automatic disqualification
  • Past marijuana use may be waivable; recent or ongoing use is disqualifying
  • Hard drugs (cocaine, heroin, methamphetamine): generally disqualifying, waivers are rare

  • Army: Most permissive — allows hand and neck tattoos. No face or head tattoos

Special Entry Programs

Advanced Rank for Education or Experience

Buddy Programs

Some branches offer "buddy deals" where friends who enlist together may receive the same basic training platoon, same first duty station, or a possible advanced rank.

Enlistment Bonuses

Bonuses range from $2,000 to $50,000+ depending on your branch, job, contract length, and current military needs. The bonus must be written into your contract to be guaranteed. If it's not in writing, it doesn't exist.

Advice for Anyone Considering Joining

  1. Take your time. This is one of the biggest decisions of your life. Don't rush it.
  2. Talk to more than just recruiters. Find veterans, active-duty members, and military families to get real perspectives.
  3. Research your specific job options. Don't just pick a branch — understand what your daily life will look like in a specific role.
  4. Get physically ready before you ship. The better shape you're in, the easier basic training will be.
  5. Get your personal affairs in order. Bills, debts, vehicle, housing, legal documents — handle it all before you leave.
  6. Understand what you're signing. Read every word of your contract. If you don't understand something, ask.
  7. Have realistic expectations. Military life has incredible benefits and real challenges. Both are true simultaneously.
  8. If something feels wrong, trust your gut. A good recruiter respects your concerns and answers your questions honestly.
  9. This is YOUR decision. Not your recruiter's, not your parents', not your friends'. You're the one who will serve.
