Stock KV Tactics?

ARGO: The KV upgraded Turret is so freaking ugly, I just could not bring myself to get it so I am cruising strait to a KV3. I would rather die looking like a tank, than win looking like a babies play blocks LOL.
Also two more things, What the hell does it say on the side of the KV2 Turret? And what guns can be placed on the standard turret?
