That’s an imperial war where local knowledge is extremely limited and your relying on sympathetic locals to let you know the terrain and who the enemy are. If that sympathetic population is low like in Afghanistan or Vietnam then you’ll walk into every ambush and never root out the enemy. In this environment guerilla war with small arms can work
If tyrrany comes to the u.s. though it’ll come with at least 30% support if not more, ironically most likely by the 2a nuts. They’ll happily point out every enemy of the state on there block and warn you about every ambush, hell they’ll probably shoot them for you.
and your relying on sympathetic locals
This would also be true of a guerilla civil war in the US though. You’d be relying on locals–people that had probably had friends and families killed by gov’t military operations and indiscriminate bombing–to help you root out insurrectionists.
Would a large number of 2A supporters be in favor of tyranny as long at it had an ® next to it? Sure. Certainly not all of us though.
