This is why I caution what people should expect when imagining a second civil war.
It's not going to be formed lines of men in pitched battles.
It's going to be warlords engaging in terror tactics with the fronts emerging along urban rural divides as opposed to state lines.
This won't be the battle of Gettysburg, it'll be the Troubles with rigged quad copter drones instead of car bombs.
Depending on who wins this election the US military isn't going to be either "side"'s ally, in fact they'll probably be the fighting parties' worst enemy since their goal is basically just going to be to kill all the people taking up arms until the terrorists and counter-terrorist terrorists knock it all off.
It'll probably lead to a purge of the most extreme folks in politics, as they'll either be found in cahoots with the terror cells covertly, or actively be leading one or more of them out of a misplaced sense that they'll be able to parry it into running the country.
It won't be glorious, it won't be honorable, it won't be anything for people to be proud of. It will just be bloody and then deeply regretted by all but the most unrepentant cretins, who still won't be able to publicly express that sentiment or risk ostracism at best, and lynching if they are discovered to have had a hand in ruining everyone's lives for however long it goes on for.
