Which small arms weapon system is considered a crew-served weapon in the Navy?

The M2 .50 caliber machine gun is classified as a crew-served weapon in the Navy due to its operational requirements and characteristics. Crew-served weapons are designed to be operated by two or more personnel, which distinguishes them from individual small arms that are intended for use by a single shooter. The M2 .50 caliber machine gun, known for its high rate of fire and formidable firepower, typically requires a team to manage the weapon effectively, including setting up, aiming, and maintaining it during operations.

In contrast, individual weapons such as the M4 Carbine, M9 Pistol, and M870 Shotgun are designed for use by a single operator. These firearms are intended for personal engagement and do not necessitate the teamwork or coordination seen with crew-served systems. The operational roles and the physical setup needed for the M2 further illustrate its classification as a crew-served weapon, as it often involves significant support elements when deployed in combat scenarios.
