What can result from a machine gunner failing to manage the weapon's rate of fire?

The consequence of a machine gunner failing to manage the weapon's rate of fire is primarily the loss of weapon effectiveness due to overheating. Machine guns are designed to sustain prolonged firing, but they have limits. If fired continuously and at a high rate without adequate pauses, the barrel can become excessively hot. This overheating can lead to various issues, including reduced accuracy, malfunctions, or even catastrophic failures like barrel warping or cooking off ammunition. Proper management of the rate of fire includes understanding the weapon's cooling requirements and firing in controlled bursts. By doing so, a gunner can maintain the weapon's functionality and effectiveness throughout the engagement, ensuring that it remains a reliable asset in combat situations.
