Which equipment is notably used by Avenger teams during their training?

The M3P .50 caliber machine gun is a key piece of equipment used by Avenger teams during their training because it serves as the primary armament on the Avenger system. This weapon is designed to engage low-flying aerial threats effectively and provides the necessary firepower to enhance the capabilities of the Avenger platform in a defensive role. The use of the M3P machine gun allows trainees to develop proficiency in operating the equipment they will utilize in real-world scenarios, focusing on target acquisition, fire control, and weapon operation under various conditions.

In contrast, while laser-guided missiles, standard infantry rifles, and rocket-propelled grenades may be relevant to infantry or other military operations, they are not primary training tools for Avenger operations specifically. The focus is on mastering the weapon systems and tactics unique to the Avenger platform, making the M3P .50 caliber machine gun a critical aspect of that training.
