I have not met a soldier who ever acted like that and in my time of service I met World War II to Iraq War Vets. Like I said before, the author should have watched the Vet interviews with the Band of Brothers DVD for a good idea on how Vets actually act.
I've met vets who did and vets who didn't.
Veterans run the whole spectrum of behavior. Some veterans are douchebags and some veterans are honorable people. Some veterans are dangerous sociopaths and some are people you could trust with your lives.
To say that "this" way or "that" way is how veterans "really" act is fundamentally disingenuous; the only thing all veterans have in common is that they're veterans of military service.
And I'll say it again:
Martin has portrayed very thoughtful, honorable military officers in his prior works. To take what appears to be one
character from this novel and claim that he always writes that way is fundamentally inaccurate at best, and dishonest at worst.
