Given a government has decided that it will release its armed troops to use deadly force against an enemy in what ever possible way they can - the ultimate insult to another human being - how can they be so hypocritical to criticize the same troops when they show a fairly subdued level of relief at having survived the conflict they have been ordered to undertake?
But you're talking about old fashioned warfare. Now we have "new warfare" where we Americans are sending ground troops to fight wars without killing anyone, except for a few unlucky folks targeted by special presidential drones. Snipers, for example, used to be a two man team, a shooter and a spotter. Now it's the shooter teamed up with a lawyer and (where communications allow) a link to a religious sensitivity consultant.
