Cupola
The raised commander's hatch on top of a turret, often the only part of a hull down vehicle that can be hit.
Also known as commander's hatch, cupolas.
A cupola sticks up above the turret roof, so it stays visible when the rest of the vehicle is behind a ridge. On many vehicles it is thinner than the turret face, which turns an otherwise impenetrable hull down position into a target.
Vehicles with small, well-armored or absent cupolas are the ones that hold ridges best, and it is one of the first things a player checks before committing to a hull down fight.
