I have a lot more faith in the troops than that ,
Not to be argumentative, but rather to understand what you mean...
In what way do you have faith? That they will continue to serve when not getting paid? That they will unquestioningly follow unconstitutional orders? That they will refuse unconstitutional orders?
The Army is a very socialistic organization - enlistment to grave health care, a roof, clothing, food, belonging and a purpose. I am not suggesting this is wrong or other than it should be, and the irony of the situation has long been noted, but it does attract a considerable number of American-value-hating socialists into the service. They usually aren't consciously there to undermine or destroy, but as you know the ideology itself is corrosive of existing institutions, and there have seen several individuals who have caused harm to the service, from the outright shooting of their fellow soldiers, to leaking intelligence info.
The question is how many of these individuals, having entered the service primarily to obtain the benefits (not to protect their country, or the American people) will continue to serve when the benefits are gone, and how many will so need the belonging and purpose that they will follow obviously unconstitutional orders? The Third Reich was built mostly of that need to belong - giving those who felt powerless and unimportant the opportunity to be strong and bully others and be lauded for it? Its Eric Hoffer's True Believers that worry me. Men like the operative in Serenity, who do evil because they believe that in doing so that they will create a "world without sin" - the Marxist Utopian world that Obama and his sheep believe will come about as soon as jerks like us stop resisting.
I think there will be a group of currently enlisted ( and another group that can be recruited) to drive those tanks. Obama's plan is to create fear and desperation- to create legions of people who feel powerless and unimportant - they just make the most motivated and loyal shock troops. But an army needs to be supplied, and post collapse the Fed will have difficulty in doing that using any other means but forceful confiscation, meaning ( I hope) forceful opposition.
Yes, some units,
because of one respected man steeping forward, may stand down. Its largely going to depend on the individual character and makeup of each group. There will be groups where this goes the other way. The $64 question is how will this break statistically. I think the best we can hope for is 80/20 on out side , but I suspect that 50/50 is probably more likly is such events were to occur.
