What is the rate of fire for the M2 .50 caliber machine gun in sustained fire?

The rate of fire for the M2 .50 caliber machine gun in sustained fire is 40 rounds per minute. Sustained fire is defined as the maximum rate at which a weapon can be fired without overheating or causing a malfunction. This rate allows for effective engagement of targets while managing barrel temperature and maintaining accuracy.

When employing the M2 at this rate, operators can conserve ammunition and ensure the weapon remains operational over extended periods. This contrasts with other rates of fire, such as rapid or cyclic rates, which are higher but not sustainable for long durations due to the risk of overheating and increased wear on the firearm. Understanding these rates of fire is crucial for effective gunnery practice and operational effectiveness in the field.
