Insurgencies in Iraq and Afghanistan have held up pretty well against the US military over all. Pervasive gun ownership in these countries prior to our involvement is a major part of this equation. I think a militia uprising in the US would fare even better because a substantial number of the members of said militia would have been trained by that very military they are fighting. I also believe that a substantial number of the National Guard units would be loyal to their state instead of a tyrannical federal government.
Let's also not forget that our country got its start by a scrappy group of farmers and tradesmen armed only with muskets and flintlock pistols that defeated the greatest world power at the time.
