The M113 is an
armored personnel carrier family of vehicles in use with the US military and many other nations.It is a fully tracked vehicle capable of limited amphibious operation in lakes and streams, extended cross-country travel over rough terrain, and high speed operation on improved roads. The M113 family has many variants and modifications that are used in a variety of combat and combat support roles. Approximately 80,000 units of all types have been produced worldwide making it the most widely used
armored fighting vehicle of all time. Although not a
tank, or even designed as a fighting vehicle, the M113 was the most effective armored vehicle of the
Vietnam War. It inspired newer generations of more heavily armored and armed
infantry fighting vehicles. Yet it remains in front-line service and production in the 21st century, and the M113 was recently declared the best in a television comparison of "top 10" armored personnel carriers and infantry fighting vehicles.
