What type of firing position is referred to as 'Gunner' in a mortar squad?

In a mortar squad, the term 'Gunner' specifically refers to the individual operating the mortar. This role is essential for the effective execution of mortar fire missions, as the gunner is responsible for aiming and firing the mortar to deliver indirect fire support. The gunner must have a thorough understanding of the mortar system, including its capabilities, limitations, and the appropriate firing procedures. This person is trained to manage the complexities involved in adjusting fire, such as considering range, elevation, and wind conditions to ensure accuracy.

The other roles in a mortar squad, while critical to the overall functioning and success of operations, involve different responsibilities. The officer in charge of the squad oversees tactics and general operations, while the individual who assists the gunner is typically responsible for logistical tasks such as managing ammunition and helping with the setup. The rounds supervisor focuses specifically on the management of munitions used in the operation. Hence, the gunner’s unique function in operating the mortar and executing the fire mission establishes why this is the correct designation within the context of a mortar squad.
