A CAAT is not a formal unit, but an ad-hoc organization of the existing weapons company. • Vehicle commander (VC) - The vehicle commander makes all decisions regarding the vehicle and its inhabitants. The VC will usually be on the
radio (or other communications device, i.e., laptop) and communicate directly with other vehicles. Exceptions to this rule are officers who usually have another marine use the radio. • Driver - The driver not only drives the vehicle, but is responsible for its entire upkeep and maintenance. The driver coordinates with the motor pool and its marines to ensure timely repairs and maintenance. In addition, during ship-borne deployment, the driver is responsible whenever the vehicle must be moved. During missions, the driver takes cues from the VC as to where to go and how to get there. • Gunner - The gunner maintains and operates the gun, and also provides a view to the VC from atop the vehicle. The gunner is quite visible in the turret of the vehicle, and so he can also be a communicator to any people outside the vehicle. • Corpsman - The platoon's corpsman is a U.S. Navy
hospital corpsman with additional field medical training. The corpsman takes a full part in operations with the rest of the team, but also provides medical assistance and coverage when necessary. • Dismount - The dismount is responsible for anything that needs to be done outside of the vehicle, such as obtaining visual information that is not possible from the vehicle's point of view. This billet may be combined with any of the other billets, except usually not for the VC or the driver. • Ammo man - The ammo man is another combined billet. When the gunner is using the gun, someone may be responsible for taking old ammo and providing the gunner with live ammo (missiles or rounds). This improves the rate of fire of the weapons system. ==See also==
