What is ack-ack gun?

Ack-ack gun, or anti-aircraft gun, is a type of artillery used for defense against enemy aircraft. These guns are designed to quickly fire rounds into the air, following the trajectory of an approaching enemy plane and detonating explosive shells near it.

Ack-ack guns have been used in various wars, including World War I, World War II, and the Korean War. They were typically mounted on a mobile platform or installed in a stationary position to protect key territories and infrastructure.

The effectiveness of ack-ack guns varied depending on a number of factors, such as the quality of the gun and the skill of the operator. Modern anti-aircraft weaponry has since replaced the ack-ack gun in many militaries, utilizing advanced technology to increase accuracy and range.
