What is the primary operation of a Cannon Crewmember?

The primary operation of a Cannon Crewmember revolves around firing artillery, particularly with howitzers such as the M119A3. This role is essential to providing indirect fire support in combat scenarios. It involves several critical tasks, including calculating firing data, loading projectiles, setting fuses, and executing precise firing commands, all of which ensure that artillery can support ground troops effectively.

Understanding the functions and responsibilities associated with firing artillery is crucial for a Cannon Crewmember, as they must be able to operate in various conditions, coordinate with other units, and adapt to tactical requirements. This capability is foundational to their role on the battlefield, making it the correct answer in the context of their primary duties.
