I would like to see an indicator in the gunsite of the panzer/T34/tiger/M8 that indicates exactly where you are pointing in relation to the front, especially when you are switching between gunner and commander positions. If I recall correctly this was a feature in many tanks.
Could be marked in degrees like a compass and be unobtrusively located in the site somewhere.
It would even be nice if there was a similiar set up when using the commanders cupola, you spot an enemy tank at bearing 270, drop into the gunners position and swing your barrel onto the same bearing and look for your target, would simulate the effect of having a commander aiding in threat location.
Or perhaps we could make Gv's joinable, so you could have a driver/machine gunner, a commander and a gunner

in those vehicles having more than 2 positions.
Imagine driving across the battle field with the driver looking out his view slit, the gunner looking thru his sight and a commander manning the machine gun and looking for both air and ground threats:aok
You see something mean and nasty lining up on you or maybe he hasn't seen you,commander tells driver to go to the right to get a hull down position and commander talks the gunner onto the target and...........
It would mean selecting a private channel to keep from confusing other GV operators in the area, but just imagine the possibilites.
