In the UK in WW2 a significant percentage of conscripted boys were drawn by lot to be sent straight to work down the coal mines instead of going into the armed services. Many of them felt ignored, forgotten, belittled or that they hadn't helped decades later. But someone had to keep the lights on and power flowing to make stuff. Even if you volunteer, when you sign up for the military you are accepting that you will be given orders and you will obey them. You might not like them, and it might not be what you signed up for, but provided the orders are legal, you do it. It's an occupational hazard, and one that ought to be pretty bloody clear to all concerned well ahead of time. Maybe I'm off base, but if you wanted a career where you don't have to obey orders, WTF would you join the Army?
