I am being told to go to PT by the command on only 4-5 hours of sleep. As a junior enlisted, how do I solve this problem?

I mean this with all due respect. Bite the bullet and go to pt. At my old unit we used to run 100+ hours a week. You got sleep in where you could. I know it sucks, but I recommend you embrace the suck and try to talk to your first line about some comp time or time to reset.

I suggest that you obey all lawful orders of those appointed over you. If you feel that you aren't getting enough sleep you could request to speak to your C.O. about it.

I can understand the disappointment of the 1st Sgt. when only 5 bodies turned out for PT. How the heck did that happen? Who was the former 1st Sgt that allowed that to occur? How did the C.O. not notice?

I can tell you that when I served the only watch that got any slack with regard to reville was the 2400 to 0400. They could sleep in till 0800. When I opted to attend a college course in town I was put on the !200 - 0440 watch. So I would go on duty at 1200, off duty at 1600. Time for meal and into town for class 1900 to 2130. Back to base in time to go back on watch at 2400 - 0400. Then sleep till 0800.
Don't be a wus.

Start with your squad leader and go from there. Let's just say your squad leader and platoon sgt don't know you haven't had sleep etc. Just a general conversation with them and I think it will go a long way. Don't be an ass to them just talked to them on whats going on. Remember when we say we are family we mean it and this is what family does you talk about things. I'm they will understand and adjust your schedule to fit the needs of the platoon and the mission.

Just do it!...
One time deal for your day, sleep at your Lunch...

I'm old school Army. When I was a junior enlisted, then an NCO, the regulation was a minimum 4 hours of sleep every 24 hours. I don't know if that regulation is still current, but if it's still the same, all I can suggest is manage your time accordingly.

You are kidding right? Suck up and get some PT in. The "new" breed is really fragile.

Suck it up buttercup. You are in the military, and that is how it works. Wait until you’re deployed and you’ve been up 24 hours straight or longer because everything has gone to hell in a hand basket. Everything you do in garrison is meant to train your mind and body for the rigors of combat. Not to mention, I’m sure I’m not the only one that can they’ve shown up to PT formation with less than an hour of sleep still drunk from the night prior and had to run a 10 miler that day. Ah the joys of infantryland.

Just do that hour of physical Fitness. How about pulling 24 hr duty on a Wednesday ending Thursday and being told to do PT, or partake in Sergeants Time Training. Dayum we done got soft

We fix all night marches, got out 20 minutes to rest and change. Thrn onto PT area and do about 30 min of that crap, now regular duty,

Easy answer....... make Pay Grade
