Marine Corps Warfighting Publication (MCWP) 3-12, Marine Corps Tank Employment, provides Marine Corps doctrine and supporting tactics, techniques, and procedures for the employment of Marine tanks in support of the Marine air-ground task force (MAGTF). Historically, Marine tanks have played critical roles in the success of the Corps' combat operations. From World War II to Iraq, the commander's ability to effectively employ Marine tanks has provided him with a devastating direct fire capability. Today, the Marine Corps' M1A1 Abrams tanks are the most lethal direct fire and survivable weapons system within the arsenal of the ground combat element.
