PTSD, stress will do this to you. Stress before deployment, stress after deployment. Fear of losing life and family. Fear of losing everything. Watching your battle buddies die in front of you in a horrific combat fight, fear, stress anger, building up until you just blow up and release the pressure. Releasing the pressure... That's all you see here.

No one knows this Marines pain except the Marines he serves with, they know. The civilians will never understand this unless they've been to hell.

We are all like the quiet guy in the car, safe, silent and still... not knowing the pains of war.
