I wasn't in US military but I served in a US unit in the Canadian Military for 3 years. I knew people who got thrown out, I also knew of plenty more who made me promise not to say anything to anyone if I was out partying with some lesbian chicks I knew. They were terrified. It really confused me but they had legitimate reason to be worried.
If you wear a uniform and you do your job and have my back. That's all that matters. If anything else is more important you should not be in the military, period.
