WW II Tractors / Bulldozers
During WW II crawler tractor / bulldozers were used by the U.S. military for combat construction in Europe, Asia, the Pacific, literally all over the world. They also served as prime movers for artillery, and for a multitude of other tasks. The crawler tractors had unsurpassed capability to move and tow in the muddy jungles of the Pacific islands which made them especially prized by SeaBees, Marine Corps and Army units in the Pacific Theater. When equipped with a bulldozer blade, they could level ground for roads and airfields as well as clear debris, construct fortifications and much more.
