It would depend on what the war was about. The most likely chain of events (and please note 'most likely' =/= 'probable') in this case would be the gradual erosion of individual rights to a point where the Bill or Rights would be pretty much nullified. Even then there would have to be some great inciting incident which would convince a vast portion of America at-large to be convinced that there was no way to resolve their grievances peacefully.
After that point...well it gets hazy. What is the ultimate goal of this civil war? I mean push-come-to-shove, going after the main perpetrators of the excesses shouldn't be too hard, which means that a new government could be elected to replace the old and rescind the offending laws.
With regard to what the military would do, chances are unless the rebel cause is demonstrably unhinged, they wouldn't do much of anything. Even so, they aren't going to nuke or bomb or shell cities where their wives, girlfriends, moms, dads, sons, and little sisters live, and unless the rebels are dumb enough to wear uniforms determining an 'insurgent' will be just as difficult (if not likely more so) here as it is in Afghanistan and Iraq. The US is simply too big to be occupied in every major city, not to mention the fact that there would be no true 'battles', but just sporadic skirmishes that would leave a lot of dead and wounded, but would be over long before any support could get there. It would simply be a long war of attrition and sabotage.
If that were to happen, commerce would freeze, much of the nation would grind to a halt and I'm willing to be those same soldiers would start to question if they're backing the right horse.
In general though...I just don't see it happening. We're either voting for a new President or a new Congress every two years, if a truly draconian law were to come into effect (under normal circumstances) it would likely be repealed/found unconstitutional LONG before anyone in significant numbers felt the need to take lives over it.
