They were absolutely required by their oaths to arrest the government, including Trump (if he didn't order the military to move that is) for not defending the constitution. Trump, as the highest law enforcement official in the land, was required to use any means or agencies necessary to arrest the government, since this did not happen, I believe that the military is too compartmentalized or too political to do their job. I like Trump, but if he did not at least order arrests, than all three branches of government, and the military have committed treason to the people and constitution of the United States.
