M15 SPECIAL HALFTRACK W/40MM CGMC 1/35
The Subject: The 40mm M15 "SPECIAL" CGMC
The Army had experimented with mounting a M1 37mm antitank gun to an early M2 halftrack soon after Pearl Harbor, but the recoil actually damaged the vehicle, and the project was abandoned. However, it was revived as the T28, which mounted the 37mm on a larger, more robust M3 halftrack. Crews complained that they lacked any sort of protection to the side (to accommodate the gun, the sides of the standard halftrack were removed), and the heavy triple-mount guns tended to break down the chassis. This was rectified in the standard production version, the M15A1 Gun Motor Carriage (GMC), which added an armored box for the crew, and replaced the water-cooled .50s with lighter and more efficient air-cooled M2HBs.
