I'm willing to bet (and probably never really know for sure), that our "modern" military are chock FULL of misleading and confusing commands and directives for a
warrior to sustain long enough to be conditioned for a combat zone, but that returning to civilian life is a surreal experience.
Our guys should be given basic enemy knowledge and allowed to kill him without asking permission from someone at a computer console.
Collateral damage is what surrendered Japan and Germany.
