Action and reaction. Combat hones skills seldom used anymore in daily life. I am not oblivious to the terror that combat brings. Courage is doing what you need to do when you are scared to death. It is not some movie character standing in the face of make-believe fire. Courage is what you call what happened AFTER you survive it. Sacrifice is what it is called when you don't.
Our troops do what they have to do even when scared. It pays for US to remember what they felt and what we call it, are not always the same thing.
I support our troops, their service, their courage and their sacrifice.
