Mack » T19
During the World War II the company Mack was kept from the producing of half-track armored vehicles, which were produced by other US companies. Meanwhile, work on such machines was started already in 20s and the Mack built the prototypes AB and AC with a tracked mover designed by Christie and Gilliland. In 1941, the company attempted to base in this sector and created the experimental half-track chassis T1 with a rear mounted 192-horsepower engine and tracks from the M3 tank. First, an automatically anti-aircraft 40 mm gun Bofors were mounted on this chassis, and then was built the armored T3 model. In 1942, the company made two prototypes of the 2.5-ton armored vehicles T19 with a rear mounted 215 hp engine Continental R6572, front drive axle and 7-ton winch. Inside there were a place for 13 soldiers. The prototypes could haul heavy guns and could reach 60 km/h.
