Which rate of fire is categorized as 'rapid' for the M240-B?

The rate of fire categorized as 'rapid' for the M240-B is indeed 200 rounds per minute (rpm). This classification is important as it helps Marines understand the operational capabilities of the weapon system in various combat conditions.

The M240-B is a versatile medium machine gun that can sustain different rates of fire — sustained, rapid, and cyclic. The rapid rate of fire indicates that the weapon can effectively deliver a high volume of fire for short periods, striking a balance between firepower and barrel overheating. Understanding these rates of fire helps in tactical planning to ensure that the weapon can be used effectively while minimizing the risk of equipment failure or damage due to excessive heat.

The sustained rate is generally lower than the rapid rate and is meant for longer engagements to conserve ammunition and manage barrel temperature. The cyclic rate is much higher and refers to the maximum firing capability of the weapon but is less sustainable in practical terms. Therefore, 200-300 rpm serves as a guideline for rapid engagements, giving Marines the flexibility to adapt their fire strategy based on the tactical situation.
