What is the sustain fire rate for the M240B?

The sustain fire rate for the M240B is 100 rounds per minute. This rate is designed to balance effective fire with ammunition consumption, allowing units to maintain a steady volume of fire over extended periods without rapidly exhausting their ammunition supplies or overheating the weapon. The concept of sustain fire is critical in combat situations, as it allows for a continuous yet manageable output of firepower that supports the unit while conserving ammunition and ensuring weapon reliability.

Understanding the sustain fire rate is essential for planning and executing operations, as it informs soldiers and leaders about how to set up fire support without compromising operational effectiveness. The other rates of fire for the M240B, like rapid or cyclic fire, are typically higher and not suited for sustained engagements where control and accuracy are paramount.
