The flip side is that many people in the military would absolutely sabotage the coup. Keep in mind that everyone in the military is bound by an oath to defend the Constitution from enemies foreign and domestic.
Purely anecdotal, but from discussion with my military friends there is widespread belief more than half of enlisted soldiers would've supported the Jan 6th coup attempt militarily. That percentage is far smaller along officers. With two exceptions though the people telling me this are officers and that will slant their view.
