>>2,3Don't worry, based Putin will sell them some extra stuff in case of civil war. A million rednecks with rocket launchers will win vs anything short of strategic carpet bombing. Tanks are very bad at urban combat and rough terrain, helicopters are vulnerable to grenade/rocket launchers and infantry would be demoralized with too much trained snipers.
Unless liberals invent some terminator robot army, they'll lose. However even if they do try them, such things will be expensive and require lots of electricity/fuel, so even that is in question if energy supplies/grids are attacked. The best cost-effective warfare solution will be likely some cheap drones, but as all aircraft they will not be armored enough to resist rifle fire, especially higher caliber stuff.
However to win a civil war with drones, liberals would have to operate them, and since they alienated the gamer demographic, i think they'll have to resort to fake gamer girls and tranny twitch streamers with noodle arms.
They will lose the war.
