Personally, the goofing around was completely tame and the casket was a training prop, not the real thing.
Death threats in this case are a bit stupid. I think reassigning her and the others to a really crappy detail should be enough.
It’s one thing to engage in gallows’ humor. People who deal with dead and dying people, no matter how well-adjusted they are need some kind of outlet from time to time to keep from going crazy. But these Guardsmen should have been much more discreet about it instead of taking pics of each other acting like classless idiots.
This behavior is stupid but not as stupid as the morons making death threats or how about the Secretary of State that lied to parents at a real funeral!!!
Thing is, that women fought to be able to be part of our military and now this wench proves why (to critics of women in the military) women don’t belong.
