As another poster correctly pointed out, anything like this would HAVE to originate at the very top. And as another poster rightly remarked, these guys are as political as anyone on Capitol Hill or they wouldnt have made it to the top.
Having said that, they ALSO have NON-MILITARY families and extended families who would suffer in a renegade, Constitutionless, totalitarian regime which history teaches only gets worse and more oppressive with time.
I sincerely believe that these traditionally honorable and honor bound men would do what they felt was necessary to keep that from happening lest their failure to act make a total mockery of their careers and lives.
The few Ive ever met among them the late General George Olmsted (my wife worked for him in D.C. back in the 60s) and the late General Lew Walt, USMC would rather eat their service pistols than stand aside while the nation and the Constitution to which they swore that oath was systematically dismantled (as it is as you read this).
Just my opinion.
And in your opinion what would be the answers to any of the questions I posed earlier.
