The M113 is a fully tracked armored personnel carrier that has formed the backbone of the United States Army's mechanized infantry units from the time of its first fielding in Vietnam in April 1962. The M113 was the most widely used armored vehicle of the U.S. Army in the Vietnam War, earning the nickname "Green Dragon" by some people, but largely known as an APC and ACAV (armored cavalry assault vehicle) by the allied forces, as it was used to break through heavy thickets in the midst of the jungle to attack and overrun enemy positions.
The M113 was developed by Food Machinery Corp. (FMC), which had produced the earlier M59 and M75 Armored personnel carriers. The M113 bore a very strong resemblance to both of these earlier vehicles. The M75 was too heavy and expensive to be useful; its weight prevented amphibious capability, and being transported by air. The lightened M59 addressed both of these problems, but ended up with too little armor, and was unreliable as a result of efforts to reduce its cost.
The Army was looking for a vehicle that combined the best features of both designs, the "Airborne Armored Multi-Purpose Vehicle Family" (AAM-PVF). of all-purpose, all-terrain armored fighting vehicles FMC had been working with Kaiser Aluminum and Chemical Co. in the late 1950s to develop a suitable aluminum armor. Use of this armor could produce a vehicle that provided the protection of the M75, and the light weight and mobility of the M59.
FMC responded with two proposals; two versions of the aluminum T113 - a thicker and a thinner armored one - along with the similar but mostly steel T117. The thicker-armored version of the T113, effectively the prototype of the M113, was chosen because it weighed less than the steel competitor, while offering the same level of protection. An improved T113 design, the T113E1, was adopted by the U.S. Army in 1960 as the M113. A diesel prototype T113E2 was put into production in 1964 as the M113A1, and quickly supplanted the gasoline-engined M113.
