What are the different firing rates available for machine guns?

The correct answer identifies the three established firing rates for machine guns: sustained, rapid, and cyclic. Understanding these firing rates is crucial for effective machine gun employment in various combat scenarios.

Sustained fire refers to a rate that allows for the machine gun to fire continuously without overheating, typically around 100 rounds per minute. This rate conserves ammunition and minimizes barrel wear, enabling effective suppression of enemy forces over extended periods.

Rapid fire is a faster rate, generally around 200 rounds per minute, utilized during offensive operations or when immediate firepower is required. This rate demands a careful balance to manage barrel heat and maintain accuracy while delivering a high volume of fire.

Cyclic fire represents the maximum rate of fire achievable by a machine gun, often cited as around 600 rounds per minute or higher, depending on the specific weapon system. This rate is not practical for sustained operations due to rapid overheating but can be useful in short bursts when overwhelming enemy positions or in defense.

The other choices suggest different terms for firing rates that do not align with the standard terminology and understanding of machine gun operations. Understanding these firing rates is essential for effective strategy and operational success on the battlefield.
