This M9A1 armoured half-track was on display at Bovington.
The M9 half-track was a half-track produced by International Harvester in the United States during World War II for lend-lease supply to the Allies. It was designed to provide a similar vehicle to the M2 half-track car.
It had the same body and chassis as the M5 half-track but had the same stowage and radio fit as the M2 half-track. 3500 were produced by the end of World War II.
The M9A1 variant of the M9 matched the improvements made to the M2, M3, and M5, changing to ring mount machine gun mount and three pintle machine gun mounts.
