The C15TA Armored Car was built by the Canadian's to carry load during WWII. It was developed from the Otter (Armored Car) and was built by General Motors Canada in line with the concept for the American M3 Scout Car.
It was used in the northwest European campaign during the World War-II by the Canadian and British units as an armored personnel carrier. It also served as an ambulance during the conflict.
After the war, the countries that took to using the armored car units included Belgium, Denmark, Norway, the Netherlands, Spain, the French, Portugal, South Africa and even the Federation of Malaya.
As seen in the top photograph, some of these vehicles were still in use in the 1960's.
They finally became obsolete and disappeared from the ARVN inventory with the introduction of the U.S. manufactured Cadillac Gage Armored Commando Car (V100).
