International Harvester TD-18 Tractor / Bulldozer (G-101)
The TD-18 Tractor / Bulldozer was a designated prime mover for heavy artillery such as the M2 155mm "Long Tom". The TD-18 was especially useful in the mud and jungles of the Pacific Theater where only a tractor crawler could move the heavy artillery. With a bulldozer blade, the TD-18 was used to build roads and fortifications as well as to breech enemy positions. It is reported that the SS President Coolidge, a luxury liner converted to troopship, had 120 IH TD-18 bulldozers in cargo when it was sunk at Espiritu Santo in 1942, while carrying reinforcements for Guadalcanal.
