" Not that I expect 0% accidents during a war, but there were some definate errors made in planning out a (relatively) untrained maintenance group driving around in a hostile area for so long."
There should have been at least a sarg who could read a map and compass. I don't know the details of the story-haven't followed it. As far as planning goes it doesn't amount to much. They got lost. They should have immediately reoriented when they determined they were out of radio contact, or hadn't reached their objective yet. Maybe they did reorient and sarg led them futher astray.
PFC Lynch wasn't responsible for the overall screwup. She does have a sarg for a fiance(husband?) and lots of military friends. She should at least speak w/o trashing, or allowing the military to be trashed by such leftist enemies. IOWs, even though she's ~20, she should think first before opening her mouth.
If you're over 20, then you should realize that this is a liberal trashing of Lynch and the military and treat as the propaganda it is. Read the article again and tell me where she was angry. There's no anger in what she said, she is simply saying the story was wrong .
