The KAMAZ-63969 Armored Personnel Carrier is a prototype variant of the KAMAZ-63968 Typhoon-K Armored Modular Vehicle that was unveiled in 2013, the same time as the production 63968 vehicle.  It was quite different in appearance from the 63968, most notably the front cab arrangement.  Also, based on some information available it was built with a non-modular rear hull option.  To date, there is no information this variant was ever developed beyond one prototype.
