What if the tanks and apcs were as mechanical as the choppers? Like hear me out. Instead of pointing your arm out in the direction you wanna shoot, have the pilot in the cockpit adjusting the turret and driving with physical controls. I think that could be pretty interesting to do. But since being inside the cockpit would have a visibility disadvantage, maybe increase the durability or increase the damage of the ground vehicles. This game is really fun and i love how immersive the choppers are. I would love smth similar for the tanks, apcs, and anti air weapon.

For example:
Tank; (described above)
Apc; maybe the passengers in the apc are able to see each other in the passenger area, like the big carrier chopper,
Anti-air; same thing as the tank, but with more visibility, maybe a screen on the interior to show what the turret sees, and a radar for friendly and enemy aircraft?
