M1064A3 APC

Armed with an M121 120mm mortar, a variant of the M120 mortar. Still in front line service.

The M113 is a fully tracked APC. The vehicle was first fielded by the US Army in Vietnam in April 1962.

The M113 introduced new aluminum armor that made the vehicle much lighter than earlier vehicles; it was 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. Army, the M113 series have long been replaced as front-line combat vehicles by the M2 and M3 Bradleys, but large numbers are still used in support roles such as armored ambulance, mortar carrier, engineer vehicle, and command vehicle. The U.S. Army's heavy brigade combat teams are equipped with approximately 6,000 M113s and 4,000 Bradleys.

The M113's versatility spawned a wide range of adaptions that live on worldwide, and in U.S. service. These variants together currently represent about half of U.S. Army armored vehicles. To date, it is estimated that over 80,000 M113s of all types have been produced and used by over 50 countries worldwide, making it one of the most widely used AFV of all time. The Military Channel's Top Ten series named the M113 the most significant infantry vehicle in history.

The U.S. Army planned to retire the M113 family of vehicles by 2018, seeking replacement with the GCV program, but now replacement of the M113 has fallen to the Armored Multi-Purpose Vehicle (AMPV) program. Thousands of M113s continue to see combat service in the IDF, although as of 2014 the IDF was seeking to gradually replace many of its vehicles with Namer APC's .
