🛡️ Military police & security

What they do
This field is military law enforcement and security. Military police and security forces patrol installations, control access, respond to incidents, investigate, and provide force protection; corrections specialists run detention facilities; investigators handle felony-level cases; and working-dog handlers team with military police dogs.
Expect law-enforcement training, firearms qualification, and shift work.

ASVAB areas that matter
Word Knowledge (WK) and Paragraph Comprehension (PC) with Arithmetic Reasoning (AR); physical and background standards also apply. Your AFQT score decides whether you can enlist; individual subtests combine into “line scores” that set which jobs you qualify for. Prepare with our free ASVAB practice tests.
How it transfers to civilian work
A strong pipeline into civilian and federal law enforcement (police, sheriff, corrections), private and corporate security and loss prevention, and federal agencies (TSA, CBP, FBI, U.S. Marshals). Dog handlers move into K-9 and detection work. Credentials: state POST law-enforcement certification, security-guard licensing, background/clearance.
