Each battalion's weapons company includes four platoons of four HMMWV-family third-generation M1152 ECV armament carriers. Each vehicle has a multipurpose mount that can accept a .50 caliber M2 (machine gun), 40mm MK19 grenade launcher, or BGM-71 TOW antitank-antifortification missile. There is an artillery battalion with two batteries of 105mm howitzers and an AN/TPQ-36 (V)8 artillery locating radar. 
The fire support platoons in each maneuver company connect to the Advanced Field Artillery Tactical Data System (AFATDS). The scout unit has extensive target acquisition capability for the indirect fire weapons.
