That's your opinion. My son has a family to support and as an infantryman has little to offer in the minds of potential employers. The days of "patriotic" soldiers is greatly diminished, if not gone entirely.
Gutless? Three combat tours.
Selfish? family to support.
Unprincipled? Doing what he can from within, sublimating his own desire to get away from the "special" so called soldiers for the good of his troops. Liking it? Not even a little bit.
Cowardly? That's an insult to my son and the good troops who have to choose among bad and really bad options.
It's pretty cowardly to sit behind your computer and call good men cowards. An apology is in order.
