M4 High Speed Tractor

The M4 High Speed Tractor was a tracked prime mover developed in World War II for towing heavy artillery. It was built on a tank-derived chassis, providing the off-road capability needed to handle difficult terrain. The vehicle typically hauled 155 mm guns or 8-inch howitzers, along with their crews and ammunition. Its durable design kept it in service after the war, proving valuable in both military and civilian roles.
