I have carried this quote with me since about 1991. To me it says it all….
“..And men don’t exhibit uncommon valor for scraps of metal and ribbon to pin to their uniforms. They don’t do it for a couple of hundred bucks a month they’re paid. They don’t do it because they want promotions or because they’re afraid of a court-martial. When the chips are really down, they don’t even do it for the Constitution of the United States. That may be why they enlist, but it isn’t why they become heroes. When the chips are down, they do it for each other…” (William Roskey, 1988, “From the novel Muffled Shots”}
