The US Marine Corps’ AAVP7 Amtracs have been their primary ship to shore amphibious armored personnel carrier for a long time; the AAV7A1 was initially fielded in 1972, and underwent a major service life extension program and product improvement program from 1983-1993. The Expeditionary Fighting Vehicle was the USMC’s plan to replace the aging AMTRACS (lit. AMphibious TRACtorS), which saw extensive service deep inland during Operation Iraqi Freedom.
The personnel version of the new EFVs would carry a crew of 3, plus a reinforced rifle squad of 17 combat-loaded Marines. A high-tech weapons station would provide firepower, via a stabilized ATK 30mm MK 44 Bushmaster cannon with advanced sights to replace the AAV’s unstabilized .50 caliber machine gun. A command variant would carry an array of communications and computer systems and staff personnel. The EFV remained the U.S. Marine Corps’ top land acquisition priority, even as its price tag and development issues cut its buy sharply. Push finally came to shove in 2010, however, as the USMC realized that it simply couldn’t afford the vehicle, or its performance.
