US military has ~1.4 million soldiers
Even if half of those soldiers defected (not likely) they still won't have the resources and logistics to actually take anything. Shit, they wouldn't get as far as a plan to take anything, they'd just get bombed by our flying killbots.
If you seriously believe that a citizen militia, even one with army deserters, would stand a modicum of a chance against the US military you are a legitimate moron. Not as a joke, not as an insult, if you believe what you're posting you have at least mild mental retardation.
