What is the sustained rate of fire for a 120mm mortar after the first minute?

The sustained rate of fire for a 120mm mortar after the first minute is indeed 4 rounds per minute. This rate is established to ensure a consistent and effective delivery of fire while allowing for the necessary cooling of the weapon system, as well as for the crew to maintain their operational tempo without overwhelming fatigue.

Understanding the importance of the sustained rate of fire is crucial for effective planning and execution in combat operations. While the initial firing rate can be higher due to the urgency of the situation, it stabilizes to a more sustainable level to preserve ammunition and ensure the crew can continue to function effectively over extended engagements. The capability to maintain a steady fire rate is vital for providing ongoing support to ground forces while minimizing the risk of component failure due to overheating or excessive wear.
