Morning. MP (Army) currently deployed. 12 years of service. Army MP's do a whole lot of different things when at home and deployed. Its ever changing from fort to fort (lots of DOD police coming in), but yes while not in the field or deployed you can fulfill LE duties, i.e. patrol. With specialized classes you can become K9, Traffic, and MPI. These are the most common. While on deployment you could end up pulling detainee guard, convoy support, Area Security, Route Recon or general LE duties among other things. Yes you would still be LE in a deployed environment if assigned.
Can’t really describe a day in the life of…. But I can tell you, while in the states, not deployed, I worked a month of LE (writing tickets, arresting DUI’s, responding to shoplifting calls, ect), then went to the field for a month, working on all the other stuff. While overseas (Korea) not deployed, it was basically the same, with more emphasis on the field.
It all depends on what fort or camp you go to and what unit you are assigned to. Some places have all LE duty units and all field units, while others have a 50% to 50% split. There are also Corps MP’s, Airborne MP’s, and Air Assault MP’s. The diversity in the MP MOS is apparent.
The Air Force side from what I have seen while working with them….. Do basically the same LE job as the Army. They do place a greater emphasis on the guard duty of facilities, planes ect. I am unsure of what, if any, field work they may do.
Go talk to recruiters. Look at official sites on the internet. Gather all the information you can before you sign something, should you chose to do so. Take someone who has been in the military and has a little knowledge of how everything should work if you sign papers. My two experiences with recruiters (yes two, I signed up, got out and came back in) they have been nothing but professionals doing their jobs for the United States Military. Good luck in your choices.
To Roadkill, I made SGT (E5) in about 3.5 years. I think your experience not earning rank was due to the rules and regulations of the National Guard. From what I understand the NG only promotes people when they have a position open. No position, no promotion. Thanks.
