Roles in the Corps: Field Artillery
The Field Artillery occupational field is divided into three areas of responsibility: the firing battery, field artillery operations and artillery observation/liaison.
Editors note: On June 27, 2016, Artillery Cannon Crewman was renamed Artillery Cannon Marine.
The mainstay of the Ground Combat Element is the infantry, but every Marine on the ground is ably supported by artillery, amphibious assault vehicles, tanks and combat engineers. See more roles on the Ground.
