The M48 Patton is a medium tank and was the third and final tank to be officially named after General George S. Patton. The first version used in Vietnam was the gasoline engine M48A2 but was soon outnumbered by the diesel powered M48A3 which became the most numerous US tank during the conflict. The M48A3s were conversions of earlier models so it wasn’t uncommon for many characteristics to vary from tank to tank. Some M48A3s had 3 support rollers while others had 5 and the headlight assemblies could either be the early or later type.
