It's an environment often dominated by alpha male mentalities. The military, of course, revolves around the ability to kill people and break their stuff in defence of the national interest. There is a certain mentality that comes around toughness, around self-resilience, and I have seen this too many damn times. If you were not outside the wire, on the ground and inflicting violence on the enemy personally, there is no way that your trauma can possibly be as legitimate as my trauma.
That comes from ignorance, it comes from ego, and it needs to be crushed.
