      PATA Marginal Terrain Vehicle    The PATA vehicle was a tread laying amphibian with a payload capacity of 1/¼ tons. The vehicle rode on a cushion of low pressure air bags (34 per side track) at an inflation pressure of only 1½ psig. This extremely low ground pressure allowed the vehicle to negotiate snow and extremely soft, swampy soils which immobilize more conventional track laying vehicles. In water the vehicle swam at 7 mph. Development started in 1960 and resulted in the design and manufacturer of one Research Test Bed which was delivered to the military for evaluation in 1965.A proposal for an upgraded and improved design with a payload of 1½ tons was proposed. Seven vehicles were built and evaluated by the military (Carrier, Cargo, 1½ Ton Soft Tire Tracked XM759) but development beyond the prototype stage did not occur. See SAE Paper 690190,”Marine Corps Marginal Terrain Vehicle, XM759”, Tashjian and Simmons, U.S. Marine Corp.  Figure 33
