To add anecdote to the data in a sibling comment, I was in the infantry for many years, deployed many times, saw lots of combat. The US government would have a big problem on its hands if any part of it ordered the US military to take property and/or shoot American citizens: Almost no one I ever met would follow those orders. It is a not-uncommon topic of conversation in the grand tradition of military "what if" games. But this is sort of to be expected: Civil wars are extraordinarily messy and complicated, and history bears out that no state goes into this kind of conflict with its military intact. In fact many times it's the kind of thing which triggers the civil war or coups d'etat: The army gets wind of some "unconscionable actions" by the government's ruling party, and some populist general rounds up a few of his most trustworthy subordinates, and seizes power. This is the story of human state failure.
