What is the sustained rate of fire for the M240B?

The sustained rate of fire for the M240B is indeed 100 rounds per minute. This is the rate that allows the operator to maintain effective fire over a prolonged period while minimizing the risk of overheating the barrel and ensuring accuracy. The concept of sustained fire takes into account factors such as cooling time, barrel life, and the ability of the crew to manage ammunition effectively.

In a practical sense, sustained fire is important for maintaining continuous support in a combat scenario while ensuring that the weapon remains operational and accurate. This rate is typically achieved by firing in short bursts, allowing for breaks that help to cool the barrel and prevent malfunctions. The understanding of rates of fire is crucial for staff sergeants and sergeants first class as they lead and train their soldiers on the proper operation and tactics involved in using machine guns like the M240B.
