A Combined Anti-Armor Team or Combined Arms Assault Teams (CAAT) is an organization of a United States Marine Corps weapons company where one or more platoons are operated in a detached role to conduct reconnaissance missions and combat ground armored vehicles and air defense vehicles with heavy weapons systems. CAATs often use weapon systems such as M2 .50 caliber machine guns, Mk-19 grenade launchers, and anti-armor missile systems such as BGM-71 TOW missiles and/or FGM-148 Javelins . In the Marine Corps, members of a CAAT are typically weapons company infantrymen who receive additional training in the CAAT role as well as cross training in all of the weapons systems employed by the CAAT. In addition to their usual role of dedicated anti-armor operations, CAATs are a vehicle-mounted heavy weapons quick reaction force for the infantry units they support. CAATs may also serve as security elements for a variety of military elements. Personnel A USMC CAAT is composed of 0331 Machine Gunners and 0352 Antitank Missile Gunners pulled from the Marine weapons company Antiarmor Platoon and Heavy Machine Gun Platoon, These will be led by 0365 Infantry Squad Leaders, who in turn will be led by 0369 Infantry Unit Leaders and 0306 Infantry Weapons Officers. Basic operations against armored vehicles In its most basic role, a CAAT platoon and its various sections and teams will engage armored vehicles at standoff ranges, where the enemy will be unable to effectively engage the CAATs forces. Due to the highly mobile, but lightly armored nature, the CAAT will employ ambush tactics or flanking maneuvers to engage the enemy from unexpected directions. Heavily armored vehicles such as main battle tanks will be engaged by the anti-armor missile sections, while lighter threats such as armored personnel carriers will be engaged by the machine-gun or grenade launcher sections. The machine-gun and grenade launcher sections also act as protection against enemy infantry, which anti-armor sections are very weak against. Reconnaissance Missions CAATs are often used by battalion commanders as reconnaissance platoons. This is due in part to the armor threat with the fight against ISIS being non-existent. These missions are allowed due to these teams being so mobile, along with the extensive training each member of a CAAT is cross trained in, along with the capability of members of a CAAT platoon having special training pertaining to mission specific requirements. CAAT members are also extensively trained in Military
