Which of the following responsibilities does the primary gunner have?

The primary gunner's main responsibility is to control targeting and launch functions. This role is critical because the gunner is responsible for ensuring that the weapon system is accurately aimed and effectively launched at the designated target. This includes monitoring the equipment, making necessary adjustments, and coordinating with other team members to ensure a successful engagement.

Controlling targeting and launch functions involves understanding the technical aspects of the weapon system, the specific mission requirements, and the environmental conditions that may affect the trajectory or effectiveness of the munition being launched. Mastery of these elements is vital for mission success, as it directly impacts the safety and accuracy of the operation.

In contrast, roles like conducting post-launch analysis, focusing solely on logistics, or acting as a team leader, while important in their own right, do not align with the primary gunner's focus on the operational aspects of targeting and launch functions. These other roles may involve separate responsibilities that contribute to the overall mission but do not encapsulate the crucial actions expected from the primary gunner during the engagement.
