What is the sustained rate of fire for the 60mm mortar system?

The sustained rate of fire for the 60mm mortar system is 20 rounds per minute. This rate is defined as the maximum number of rounds that can be fired reliably and effectively over an extended period while maintaining accuracy and minimizing the risk of overheating the weapon system.

A sustained rate of fire is essential for infantry support operations, where the mortar might need to provide continuous indirect fire support during combat. 20 rounds per minute allows operators to maintain a steady output that can be sustained over time without compromising the effective performance of the mortar or risking damage from prolonged use.

Understanding the sustained rate of fire is crucial for planning effective fire missions and ensuring that logistical and ammunition supply considerations are adequately addressed during operations. In contrast, higher rates may be achievable in short bursts but aren't sustainable long-term, which is why they are not the correct answers in this context.
