Xingbao M113 Armored Personnel Carrier X06050

The M113 is a fully tracked armoured personnel carrier (APC) that was developed and produced by the FMC Corporation. The M113 was sent to United States Army Europe in 1961 to replace the mechanized infantry's M59 APCs. The M113 was first used in combat in April 1962 after the United States provided the South Vietnamese army (ARVN) with heavy weaponry such as the M113, under the Military Assistance Command, Vietnam (MACV) program. Eventually, the M113 was the most widely used armoured vehicle of the U.S. Army in the Vietnam War and was used to break through heavy thickets in the midst of the jungle to attack and overrun enemy positions. It was largely known as an "APC" or an "ACAV" (armoured cavalry assault vehicle) by the allied forces.

The M113 was the first aluminium hull combat vehicle to be put into mass production. Much lighter than earlier similar vehicles, its aluminium armour was designed to be thick enough to protect the crew and passengers against small arms fire, but light enough that the vehicle was air transportable and moderately amphibious.

The M113's versatility spawned a wide variety of adaptations that live on worldwide and in U.S. service. These variants together currently represent about half of U.S. Army armoured vehicles. To date, it is estimated that over 80,000 vehicles in the M113 family have been produced and used by over 50 countries worldwide, making it one of the most widely used armoured fighting vehicles of all time
