Currently its pretty bad and needs some work. More options, for people who want no HUD or for people who want some limited HUD like no hitmarkers, penetration markers.
Make a limited HUD mode. This would:
Not show ammo count, inventory, can be showed by initiating a reload for a few seconds, or pressing a “extend HUD” button.
Show the shells a tank is currently using, or will load after the next shot will be fired. Currently it doesnt show, so you have to guess which is just bad. Make it so we see whether do we have HE or AP loaded.
Show the Turret to hull position when in a tank.
Show the amount of squad mates you have left when switching through squadmates. Its really annoying to find an engineer when all my soldiers have K98k.
