More than 600 fragging incidents were reported by the US Army in Vietnam.
“These people knew the war was pretty much lost, that they were going to be sacrificed,” said Texas A&M University history professor and Vietnam veteran Terry Anderson. “They just wanted to get out of Vietnam.”
One has been reported so far in Iraq. Therefore, the troops seem to know that the war is not “pretty much lost”, despite claims by some of said troops.
Oh, and many of the troops in Vietnam didn’t choose to join the military. They were draftees. I’m just a stupid civilian, but I’d bet that an unwilling draftee is about a thousand times more likely to consider fragging his CO than a volunteer is.
