The second shipment of two Mine-Resistant, Ambush-Protected, or MRAP, vehicles was delivered to South Korea on 7 July 2012. A C-5B Galaxy crew from the 22nd Airlift Squadron at Travis AFB, California, flew the vehicles, weighing a combined 29,000 pounds, from the base near Sacramento to Osan AB, outside of Seoul. The MRAPs augment the capability of US Army units stationed in Korea.
