Which feature is described as a small, dome-shaped, independently revolving armored turret on top of the main turret?

• A. Main gun
• B. Cupola
• C. Mantlet
• D. Gun mount

Answer: (B)

The feature described is the cupola. It is a small, dome-shaped armored station mounted on top of the main turret that can rotate independently to give the crew a wide field of view, usually for the commander. The cupola often houses vision blocks or periscopes and may carry a secondary weapon, like a machine gun, separate from the main gun’s aiming. This independence from the main turret’s rotation allows the commander to observe and respond while the turret or gunner focuses elsewhere. The main gun is the primary weapon protruding from the turret; the mantlet is the armored shield around the base of that gun; the gun mount is the mechanism that supports and moves the main gun. The cupola’s purpose is observation and optional secondary armament, set apart from the gun itself.
