They’re being ordered to do these things
Is there a menu they are ordered from?
Again, no one is making them do it. There are options for early separation & plenty of external medical/mental providers that would support their claims.
Something that they are trained to stay out of.
No, this is what they are trained to do as well. National Guard is trained to assist in law enforcement support & maintaining peace. I really don't know why you think they are only trained for disaster relief, when it is obviously not true.
