The field artillery brigade allocated to the corps augments the fires of divisions, provides counter battery fires, and performs corps-wide target acquisition functions. +Fires planners at corps echelons develop and apply radar coverage plans to ensure counterfire radar coverage. The types of missions assigned to field artillery brigades are general support, reinforcing, and general support reinforcing. These units may be attached to divisions or any BCT remaining under the corps commander’s direct command. At the recommendation of the field artillery brigade commander, the corps commander assigns missions to the artillery battalions of any BCTs currently in reserve.

A corps will usually provide additional field artillery brigade artillery battalions in a support relationship to the DIVARTY or field artillery battalions of the BCTs conducting the decisive operation.
