Comment: Personally,

I think the US military is going to be much too busy protecting their own homes and families when the SHTF.
Because if they don't, those homes and families won't be there anymore when they get back, if they ever do get home.

The idea that anybody is going to be doing what the gov't tells them to do in circumstances like that, is ludicrous.
The paychecks ain't gonna cash, the money ain't no good, violent angry mobs will be roaming the streets, and the soldiers will protect their own families and homes, and not the government slimeballs who caused it.
The gov't is on a crack trip if they think they are going to be "protected" by anybody.
