Unlike the wartime Jeep or its post-war British equivalent, the Land Rover, the Gaz 69 does not seem to have been utilised that extensively as a weapons platform. The one obvious exception to this is the 2P26 of which I only know of examples in museum but none in private hands... but then who would particularly want one? ... as it is even LESS practical than a standard Gaz
It was intended as an anti-tank missile launcher as used by motorised rifles regiments. (The same missile system would be carried by a BTR40 in a Tank regiment). I think it was used by the Soviets too but somehow most of the photographs that have survived, show it in NVA service during the 1960s. I think the idea wa abandoned pretty quickly.
(the soldier is wearing the early pattern NVA camouflage that was gradually replaced during the late 1960s and 1970s by the raindrop pattern which flooded the surplus market 15 years ago or so)
