  1. “MOS 31B will give Army soldiers the qualifications they need to enter into civilian federal, state, and local law enforcement agencies.”
    Does this mean if I am an MP in the military, when I leave the military, I am fully qualified to be a civilian police officer? This would be my goal, so, if I signed up ro enter as an MP, I could get my certifications as a civilian police officer upon discharge?

    1. Nah you would still have to go through civilian police academy and get certified / sworn in. What I was trying to convey is that you’ll have the necessary experience / education to qualify for a job as a civilian police officer. Hope this clears things up.
