What is the required pause duration after a rapid rate of fire in the M2 .50 caliber machine gun?

After a rapid rate of fire with the M2 .50 caliber machine gun, a pause of 5 to 10 seconds is necessary to allow the barrel to cool down. This cooling period is crucial for maintaining the integrity and functionality of the weapon, as excessive heat can cause damage, including barrel warping or cook-offs, where rounds can accidentally fire due to residual heat. This pause helps to prevent any potential malfunctions in subsequent firing and ensures the safety of the operator and those nearby. The cooling period is based on established maintenance protocols designed to prolong the life of the machine gun and ensure it operates effectively during sustained use.
