What is a "burst of fire" when using the MK19?

A "burst of fire" in the context of using the MK19 refers to a number of rounds fired with the same aim. This concept is crucial for effectively employing the weapon, as the MK19 is designed for automatic grenade launching, and maintaining the same aim is essential for achieving the desired impact on a target.

When multiple rounds are fired in this manner, they can create a concentrated area of firepower, increasing the likelihood of hitting the intended target, particularly when engaging area targets. This technique allows the operator to maximize the weapon's effectiveness by ensuring that successive rounds land close together, rather than being spread out due to varied aiming or firing techniques.

This definition captures the essential operational principle of using the MK19, emphasizing the importance of maintaining aim for effective targeting.
