M4 High Speed Tractor (3 in/90mm) 1/72

The 18-ton M4 high speed tractor series was developed and built by the Allis-Chalmers Manufacturing Company of Milwaukee, Wisconsin from 1943 to 1945. The design, based upon the T9 and T9E1, was standardized as the Medium Tractor M4 which ultimately became the High Speed Tractor M4. Together with the M5 and M6 High Speed Tractors they replaced the older commercial-type crawler tractors which no longer met the requirements of a modern mechanized army. The high speed tractors could carry both crew and a basic supply of ammunition. Production started in March 1943 and 5552 M4 tractors were assembled through June 1945, and 259 M4A1 tractors between June and August 1945. The 18-ton M4 high speed tractor was designed mainly as a prime mover for the 90mm antiaircraft gun and 3-inch gun.
