Eligibility notes

What 31B candidates should check.

  • Published 31B line-score figures disagree, so here is why: this page uses Skilled Technical (ST) 91, the figure the official goarmy MOS listing and military.com's Army-jobs table both carry (re-verified 2026-06-09). A number of third-party tables and forum threads instead cite ST 95 — that higher cut is an older/stricter standard that still circulates, which is why the question 'is 31B ST 91 or 95?' shows up on Quora and Reddit. The current published requirement is ST 91. Confirm the exact figure on your enlistment contract with a recruiter.
  • How the ST score is built: the Army Skilled Technical (ST) line score is the sum of four ASVAB standard scores — General Science (GS), Verbal Expression (VE = Word Knowledge + Paragraph Comprehension), Mathematics Knowledge (MK), and Mechanical Comprehension (MC). Your ST score is GS + VE + MK + MC; to clear ST 91 those four standard scores must total at least 91, so General Science and Mechanical Comprehension prep raises an ST target the fastest because they are not part of the AFQT.
  • ST is a job line score, not the AFQT percentile. Candidates must clear the Army AFQT floor of 31 before the ST requirement applies — the AFQT decides whether you can enlist, the ST line score decides whether you qualify for 31B.
  • Military Police candidates also face suitability screening (no disqualifying criminal history) because the MOS carries law-enforcement authority.

What is Army 31B called, and is it the same as "31 Bravo"?

Yes — they are the same job. 31B is the Army Military Police MOS; "31 Bravo" is how the code is said aloud, spelling the trailing "B" with the NATO phonetic alphabet. Whether you search "31B" or "31 Bravo", the requirement on this page is the same: AFQT 31 and ST of at least 91.

What ASVAB score do you need for 31B Military Police?

Army 31B Military Police requires a Skilled Technical (ST) line score of 91 and the Army AFQT floor of 31. The ST number is the job-specific requirement; AFQT 31 is the enlistment floor.

What line score does Military Police use?

31B uses the ST (Skilled Technical) composite — General Science, Verbal Expression, Mechanical Comprehension, and Mathematics Knowledge — with a minimum of 91.

Is the 31B ASVAB requirement ST 91 or ST 95?

The current published requirement is ST 91 — that is the figure on the official goarmy MOS listing and military.com's Army-jobs table (re-verified 2026-06-09). The ST 95 you'll see on some third-party tables and forum threads is an older, stricter cut that still circulates online. Treat ST 91 as the standard but confirm the exact number with a recruiter on your enlistment contract, since line-score cutoffs can move with recruiting needs.

How is the 31B Military Police ST line score calculated?

The Army Skilled Technical (ST) composite adds four ASVAB standard scores: General Science (GS), Verbal Expression (VE, itself Word Knowledge + Paragraph Comprehension), Mathematics Knowledge (MK), and Mechanical Comprehension (MC). Your ST score is GS + VE + MK + MC, and it must reach at least 91 to qualify for 31B. Because GS and MC are not part of the AFQT, prepping those two subtests is the fastest way to raise an ST score without changing your AFQT percentile.

Where do Army Military Police train?

After Basic Combat Training, 31B Soldiers attend the U.S. Army Military Police School (USAMPS) at Fort Leonard Wood, Missouri, for about 20 weeks of training in total.

How much does an Army Military Police Soldier get paid?

Pay is by rank, not MOS. In 2026 an E-1 earns $2,407.20/month in base pay and an E-4 (under 2 years) earns $3,142/month, plus a $460.25/month food allowance (BAS) and a housing allowance (BAH) that depends on duty station.
