First deployed in combat in Vietnam, the M551 Sheridan is the first US tank to be fully amphibious and also airborne capable. Although maintenance problems and issues with the gun-launcher system caused the M551 to be withdrawn from most active Army units in the late 1970s, it continued to serve the 82nd Airborne Division as the only armored vehicle in the Army's inventory that could be air dropped.
