context_page_description: The M113 is a fully tracked armored personnel carrier that was developed and produced by the Food Machinery Corp. The M113 was sent to United States Army Europe to replace the mechanized infantry's M59 APCs from 1961. The M113 was first used in combat in April 1962 after the United States provided the South Vietnamese Army with heavy weaponry such as the M113, under the Military Assistance Command, Vietnam program. Eventually, the M113 was the most widely used armored 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" by the allied forces.
  The M113 was the first aluminum hull combat vehicle to be put into mass production. Much lighter than earlier similar vehicles, its aluminum armor 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.
  In the U.S.
context_section_description: Its weight allows the use of a relatively small engine to power the vehicle, a Detroit 6V53 V6 two-stroke diesel engine of 318 cubic inches (5,210 cc) with an Allison TX-100-1 three-speed automatic transmission. This allows the vehicle to carry a large payload cross-country and to be transported by fixed- and rotary-wing aircraft. Original production M113s can swim without deploying flotation curtains, using only a front-mounted trim vane; they are propelled in the water by their tracks.
