How many rounds per minute can the M252 fire at maximum rate for 2 minutes?

The M252 mortar can achieve a maximum rate of fire of 30 rounds per minute for a limited duration, specifically up to 2 minutes. This high rate of fire is typically utilized in combat situations where rapid response is essential. The design of the M252 allows for this increased fire rate, incorporating a quick barrel change and efficient operation procedures that facilitate rapid loading and firing.

This fire rate is significant because it enables indirect fire support to deliver a large volume of munitions on a target in a short timeframe, providing critical support during engagements. The capability to fire at this maximum rate is contingent upon the crew's proficiency and the availability of ammunition, emphasizing the importance of training and logistics in mortar operations.
