Currently in the game, many tanks allow the commanders to peak out for a better view or even to use a machine gun on the top of the tank. The commander is vulnerable in this position and can easily be killed. When the commander is killed, you can replace the commander with another crew member. However, the only way to do this is to either have all crew exit the tank, or swap your gunner or driver to that position, even if you have other crew members in the tank. I propose having some way to have the other crew members swap to the commander position without having to put your tank at such extreme risk. This would make replacing the commander much more fluid.
currently with the way crew knockouts behave, its annoying to play tanks because you are constantly getting switched to the driver and forced to manually switch seats, it should be automated like warthunder, you should just lose control while of firing/traversing while they change
