I did a few cycles while I was in the military. It really depends on your chain of command and maybe if they like you or not. I was always upfront with all of them and told them before I started and let them know when I was off and they never had a problem with it at all because I didn't let it impact work performance, if anything it made me better since I was in a combat MOS. But that's the risk you take I suppose, I wouldn't complain about snitches when you are the one who chose consciously to do the wrong thing, they were just doing the right thing.
