This sort of thing is more of a practical problem really. From my experience (this is US centric, I do know other countries do things differently) it would be the rare trooper who could think they way you're suggesting. Most of them are still really young.

Troops are kept occupied so they don't start axe throwing contests in the woods while facing each other to see how close they can get it to the other person's head.

Or make MRE bombs.

Or gather all the piss jugs together and deliver them unto the First Sausage.

It has nothing to do with philosophy and everything to do with having 100s or 1000s of barely adult people all grouped together with nothing at all to do but invent their own 'fun'.

NOW. The VA in the US exists to provide what you're suggesting. Bored, disgruntled, or out of work veterans are extremely dangerous. They're more mature, link problems to actual causes, and can spontaneously organize.

Look up the Bonus Army to see what veterans get up to when pressed.
