Which of the following options describes the proper range for the muzzle velocity of an M249?

The proper muzzle velocity for an M249 machine gun typically falls within the range of 2800 to 3200 feet per second. This velocity allows the M249 to effectively deliver rounds at a speed conducive to maintaining accuracy and maximizing the effectiveness of the ammunition over distance. Muzzle velocity is a crucial factor in ballistics, as it influences the trajectory and impact of the round, making this range particularly appropriate for the tactical roles assigned to the M249, which include providing suppressive fire and engaging a variety of targets. Understanding this information is essential for infantry soldiers to ensure proper engagement and effectiveness during operations.
