The M113 is a lightly armored, full tracked, air transportable vehicle designed to carry personnel and cargo.The vehicle is built from high strength aluminum and can operate both on and off road and in water.  The M113 was designed to carry infantry into the battlefield where they would dismount for combat. The M113 was developed and produced by Food Machinery Corporation.  The aluminum hull made the vehicle light enough to air transport and moderately amphibious, yet provided protection for the crew against small arms fire.  

The M114 Command and Reconnaissance Carrier is a Vietnam War-era tracked armored fighting vehicle, used by the United States Army. It was manufactured by the Cadillac Division of General Motors in the early 1960s. The M114 was designed to be fast and stealthy for use in the reconnaissance role. 

The M59 was an American armored personnel carrier that entered service in the spring of 1954 replacing the M75. It had three key advantages over the M75: it was amphibious, had a lower profile, and was considerably cheaper to produce. Production ended in 1960, by which time approximately 6,300 had been built.
