Development of Armored Personnel Carrier M113A1E1

This paper discusses the development of an improved armored personnel carrier, the M113A1E1 for the U.S. Army. This vehicle is an improved/modernized version of the standard M113A1-APC. The development included improving the suspension, increasing the horsepower, improving the cooling, changing the drive train and driver's controls, and improving personnel safety by moving the fuel tanks to an external location. Prototypes were built and are undergoing development and operational testing at U.S. Government proving grounds.
