What is the recommended number of rounds per 100m when using the M224 or M252?

The recommended number of rounds per 100 meters when using the M224 or M252 mortars is four rounds. This guidance is based on the need to saturate the target area effectively, ensuring that the desired effect is achieved, especially in combat scenarios where accuracy and firepower are crucial. Mortar crews aim to deliver a sufficient volume of fire to ensure that the rounds land within a lethal range of the enemy target, effectively suppressing or neutralizing threats.

Utilizing four rounds also allows for considerations such as potential dispersion of rounds and variations in the terrain or enemy positioning. The increased number helps mitigate the effects of these factors, ensuring that the maximum intended impact is realized.

In contrast, fewer rounds, such as one, two, or three, may not provide enough coverage to guarantee the necessary effectiveness against a target, especially in dynamic and unpredictable combat environments where the enemy may be able to maneuver or react to fire. Thus, the established protocol of four rounds per 100 meters reflects a tactical approach to maximizing the effectiveness of mortar fire in various operational contexts.
