Dragon Wagon is the second in a series of titles covering the U.S. Army’s Heavy Tank Transporters. The first volume covered the M25/M26 Pacific family of vehicles and trailers during their service in WWII and Korea. Part 2 picks up the story with the successor to the Pacific; the magnificent 10-ton M123 tractor. The unarmored M123 soldiered on through the 1950s and Vietnam while paired with the modernized M15A1 and M15A2 trailers from WWII. It was also paired with the next generation of heavy trailers, the M747. Also covered is the rare and unusual M746 tractor with service pictures of its brief career. Photo coverage includes lavish color shots of the M123 in Vietnam, as well during development and testing.
