Choose your weapon.
Are you still active duty? I don't know about Bragg but most bases are now (and have been for a while) civilian contract security/special police at the gates and in some instances augmenting the MP/SP element on post.
No. I'd venture to guess that most of those bases don't have active duty combat arms units like the Infantry to farm out the crappy detail to for cheap.
Even our MPs didn't do gate duty post 9-11. We did, and the job rotated from unit to unit a month at a time.
Luckily I was medical/dental and didn't have to pull that duty except one time and that was cut short. In 73 I was in Panama and we squids were assigned to do gate duty at the Marine Barracks for the Marines birthday. I had a late shift (don't remember what time) but about an hour into it Gunny and a couple of corporals showed up at the gate three sheets to the wind. Gunny took one look, parked the car (yes they were driving), told one of the corps to take over gate duty, took me back into the gate house (not a shack, an actual gate house), poured me some coffee, pulled out a flask then stiffened the coffee. I did protest, didn't really want an article 15 for abandoning my post and drinking on duty but all Gunny would say is:" Doc, you've been properly relieved now drink up. Who's gonna argue with the gunny? Not me. We sat there drinking "coffee" and shooting the shit until the relief arrived.
We got tagged with it at Schofield after 9-11. There weren't enough MPs to guard the gates. It screwed everything up, the training schedule, PT, etc, and we loathed it. My guys were always having to deal with some NCO trying to pull rank on them. The worst were actually the MPs. It got so bad, that I started to pull gate duty with my guys in case I had to line out an E-7.
I certainly don't miss that about the Army.
