What is the nomenclature of the 60mm mortar's boresight kit?

The correct nomenclature of the 60mm mortar's boresight kit is indeed M225A1. The M225A1 is specifically designed to assist operators in aligning their mortars accurately for targeting. It includes a laser and a telescope to ensure precision aiming of the mortar tube, which is crucial for the effective engagement of targets while minimizing the risk of error. This system contributes to the overall effectiveness of mortar operations by providing a reliable method for boresighting, ensuring that rounds hit within the desired impact area.

The other options do not pertain to the boresight kit for the 60mm mortar. The M224A1 refers to a different mortar system, the M115 is not a recognized nomenclature associated with mortars, and the M170A1 is another piece of equipment not related to the 60mm system. Therefore, understanding the specific roles and nomenclature of the equipment is critical for effective training and operational success.
