We've done a lot of publishing on the old South African military and have come to admire it very much. The old South African Army deployed a variety of interesting vehicles including the Casspir, a kind of APC and the Ratel, a wheeled armored vehicle with a 90mm gun. They also deployed Ratels armed with missile launchers.
An FB friend, Mr. Bruce Allen sent along this Youtube clip of a ZT3 armed Ratel fighting Angolan tanks during the Lomba River phase of the Battle of Cuito Cuanavale:
By the way, the third book in the World War 1990 series takes place in Africa with the SADF fighting the Angolans and Cubans. Plenty of Ratels in that one,
