Does the military still have KP?

In 1970, a gang of we EM were living in an apartment just of post Ft Sam Houston TX, and for some reason were later to formation one morning (we weren't approved to live off-base, so still maintained areas in the Co. barracks) and so the First Shirt had us 'absent' and was pretty fried at us. He gleefully gave we four E-5's KP for the next Saturday -- a day off except for NCO duties -- which was pretty effective discipline!
I was pretty mad, and did a slow burn until reporting to the mess hall at eleven am for my penatly. Well, I should have guessed it when none of the other three showed up; even the First didn't know that our policy was that no E-5 and above had to pull KP. The mess SGT didn't know about it anyway (!) and just put me in-charge of the sign-in desk for lunch, and after I ate, said 'Okay, beat it'. E-5 and above ate at the Officers Mess (same kitchen, nicer lunchroom) because our EM room was swamped with Medical Corps trainees. Didn't have to bus our own tables, and it was much quieter!
Boy, did my buddies have the horse-laugh on me "Old straight arrow Humble; actually showed up and did his kitchen police!" Of course, nothing was ever heard again about the gig! Virtually all KP at Medical Field-Service School was done by civilians wage-board employees, even for the RM.

I was aPFC. 18 yrs old A marine at camp Lejune in 1960. I pulled 1 month of mess duty from 0400 t0 0700 every day. We went to the rifle range for a week to qualify, I pulled 2 weeks mess duty there, I washed pots and pans for 2 weeks. It goes on your record book I was lucky in 4yrs thats all the mess duty I had too do. Aboard Ship mess duty was three months if you were a Floating Battalion, for 6 months. I must mention guard which I pulled quite often 4hrs on 8hrs off and if a person was headed for the Brig a Marine from his unit was the Chaser He was handed a 45 cal pistol and duty belt and told "if this prisoner gets away, you will do his time. If a person from the unit was courtmartialed it was read out in company formation. Semper Fi.. .

The Air Force still has, just ask their valets.

I learned a lot of lessons as a DRO and Pots and Pan man at Ft Polk, LA, but didn't pursue it as a MOS

In Korea in the 1980s we had contractors in the DFAC, we pulled KP in the field. A week or so in Korea, I was still inprosessing. My squad leader tells me after first formation report to the DFAC for KP. Odd order but I after first formation I go to the DFAC, find the mess sergeant and tell him my squad leader told to report for KP. He gives me a funny look and tells me to sit down. A few minutes later he comes back. He says “See those guys? I pay them to do KP” “In our unit if you are told you have KP, that means go hide in your room until final formation, and don’t try going anywhere because you will get caught.” Seems my squad leader had other matters to attend to and needed me to hide for the day.
