“Russian AA/artillery unit received 6 Tunguska air defence vehicles from MoD, likely from long conservation followed by major repairs - as a result, all six vehicles are disfunctional. In the full version of the video, the reporter states that upon reception, three vehicles were running but after a 30-km march all broke down with major suspension problems, another two suffer from armament control system malfunctions, and a sixth is too dangerous to even start. None of the six transport-reloading vehicles (TZM) were functional either.”
