Gun turrets are protective structures that house firearms, allowing them to rotate and aim at targets from various angles. They are commonly used in military applications, such as on ships and fortifications, to provide defensive firepower against enemy threats. The design helps shield the operators from incoming fire while enabling them to engage targets effectively. In naval warfare, gun turrets are often mounted on battleships and cruisers, providing significant fire support. They can be equipped with different types of weapons, including cannons and machine guns, depending on the vessel's mission and operational requirements.
