What is a common characteristic of both the Mauser and GAU-22A?

The Mauser and the GAU-22A share the common characteristic of utilizing explosive projectiles. This feature is significant as explosive projectiles are often designed to maximize damage upon impact, thereby enhancing the lethality of both weapons in air combat scenarios.

The Mauser, specifically in its more modern iterations, employs ammunition that can include explosive rounds, allowing for greater effectiveness against various types of targets. Similarly, the GAU-22A, which is a rotary cannon used in air-to-air roles and other applications, can fire rounds that contain explosives to increase their destructiveness.

Other characteristics mentioned do not apply as broadly; while both weapons may have high rates of fire, the specifics can vary greatly based on the model and intended use. The caliber of the Mauser and GAU-22A also differs, as does their primary design purpose, making the selection of explosive projectiles the most relevant shared feature.
