A Cannon Crewmember is an important part of the Army's success on the battlefield. Artillery teams are used to support infantry and tank units in combat, but also have responsibilities during peacetime. Cannon Crewmembers work on cannons known as 'howitzers,' a heavy artillery machine piece with single-barrel firing capability.

A Field Artillery Automated Tactical Data Systems Specialist (FAATDS) is an important member of the Army's field artillery team. FAATDS Specialists are primarily responsible for operating the Advanced Field Artillery Tactical Data Systems for both Cannon and Multiple Launch Rocket Systems (MLRS). Field Artillery Automated Tactical Data Systems Specialists play a critical role in the safe, accurate, and lethal delivery of the Field Artillery's various fire support systems. Both cannon and MLRS systems are used to support infantry and tank units in combat.
