Which type of projectile is fired from the Mauser?

The Mauser is specifically designed to fire 20mm caliber projectiles, which includes various types such as incendiary rounds, tracer rounds, and others, but not in the sizes listed in the provided options.

The choice indicating 27mm explosive shells does not correspond with the standard ammunition types associated with the Mauser, as this weapon operates with a 20mm caliber, and explosive projectiles typically fall under the 20mm designation. The confusion might stem from the various applications and adaptations of the Mauser system, but in the context of the available choices, the primary caliber recognized is indeed 20mm.

Understanding the types of rounds, their purposes, and the specifications linked to the Mauser is essential. Incendiary rounds are designed to ignite target materials, tracer rounds provide visual tracking for accuracy, and other designated calibers do not apply to this weapon system. These nuances highlight the critical nature of recognizing the correct specifications for military systems and their ammunition.
