Which rate uses a 6-9 round end burst with a 10-15 second pause?

• A. 240 sustained rate
• B. M2 sustained rate
• C. M2 rapid rate
• D. 240 cyclic rate

Answer: (B)

Understanding how heat and burst control work with the M2 heavy machine gun is the key idea here. The pattern of firing six to nine rounds and then pausing for 10 to 15 seconds is how the sustained rate is implemented. This approach keeps heat buildup in check while allowing the gunner to maintain fire for a longer period, which is exactly what “sustained” fire is about—steady output without overheating. The other rates don’t fit this pattern. The rapid rate involves longer bursts and shorter cooling pauses, which increases heat and reduces duration of controllable fire. The cyclic rate is continuous fire with no deliberate cooling pauses, which would overheat the weapon quickly. The label about a “240 sustained rate” isn’t the standard way the M2’s rates are described in doctrine, so it doesn’t match the defined sustained-fire concept.
