Yeah, the mentioned photo with 312 looks like a fuck up of SBU, it's a Ukrainian BUK and the photo is not appropriate. The one which is on a truck with blue stripe is the one that was used by separatists I believe.
Anyway, I don't like this journalist. Because trying to be such a mythbuster and playing obviously for one side is just nothing. If he reviewed both sides' fakes his channel would be 90% of videos about central Russian TV channels.
