This is interesting, a new film of a TB2 taking out a Grad on the Snake island Jetty, as you watch it there is a quick shot in colour looking along the jetty at the explosion, did the Russians not disable the CCTV cameras on the Jetty, if so, have the Ukrainians been able to watch their comings and goings all along? that will explain the smoke on the aerial shots where you can see smoke drifting from the jetty.
