Such a revolt would not be against just the military. It would target the entirety of the federal government: politicians, bureaucrats, file clerks and secretaries. And without people to administer the payroll, buy ammo, and pay for stuff, the army ceases to exist
A few years back, just two men (the "DC snipers") came close to shutting down DC. Visualize the effect of a few hundred individuals deciding to become quiet serial killers of federal employees.
Put more succinctly, in the movie "Fight Club" to a certain politician: "Look, the people you are after are the people you depend on. We cook your meals. We haul your trash. We connect your calls. We drive your ambulances. We guard you while you sleep. Do NOT f**k with us."
If the Federales start a “political” military along the lines of the KGB, SS, Republican Guard, etc., you the know the end is here. (Arguably, in various militarized law enforcement organizations, like the FBI and BATFE, they have already begun the process...)
