Overview
The M113 has become one of the most prolific armored vehicles of the second half of the 20th century, and continues to serve with armies around the world into the 21st century. Not without its faults, the otherwise versatile chassis of the M113 APC has been used to create almost every type of vehicle imaginable. Few vehicles ever created can claim the application to such a wide range of roles from basic utility to ballistic missile transporter-erector-launcher (TEL) to air defense to even a flame throwing vehicle.
Even beyond the myriad of vehicles created by the United States for its own use, scores of variants have been created independently all over the world. While still bear resemblance to the basic M113, even more share simply the chassis and are in many ways completely new vehicles.
