On my side, don’t use Tactical Helicopters anymore, armored cars only for defense in WW, and less Heavy Tanks due to Bastions. Regarding barrack troops never used Assault Vehicle.
i was using Field Mortars a lot with a range of 5, not anymore, too much troop space.
i like now attack helicopters, essentially with some of my army composition. Fully upgraded at library
MRL, like them but I never find a great army composition with them and slow shooting or not enough dmg
‘one my best troops now for mp is Commandos, amazing troops, can tell
