“The first Engineer units sent out were too lightly equipped; they did not have either adequate quantities of equipment or heavy enough equipment for clearing jungles and building in jungle terrain. The initial conception, in fact, was apparently that much of the construction work in the Pacific would be pick and shovel work. It soon became clear that one of the principal points of American superiority over the enemy lay in heavy construction equipment—bulldozers, cranes, rollers, graders, crushers, drilling equipment, power shovels, power saw mills, and so forth—that could do the work of many men.” – Robert W. Coakley and Richard M. Leighton, “The War Against Japan, 1943-44,” Global Logistics and Strategy: 1943-1945
