The Caterpillar D7 series medium bulldozer began service with the U.S. military during World War II. With upgrades and changes, it has been a workhorse for the U.S. Military for over fifty years, fulfilling its primary earth moving role as well as a host of other roles discovered for it, for example mine clearing with a special flail adapter kit. As is so often the case, the idea for this project is based upon a photograph showing a D7 Dozer in action during World War II clearing the wreckage of a Panzer IV from the roadway.
