The Russians have deployed SAMs in Belarus and has an operating radius that covers almost the entire theater.

According to Rob Lee's twitter it appears Grand Parent's deduction is correct because previously a Ukranian Su-27 that blew up in Kiev was being falsely reported as Russian jet.

I have to note how difficult it is right now. "Ukranian side" (it is not clear who the original disseminator network is) appear to be using footages of ARMA 3 and DCS: World overlayed with voice and artifacts from Twitter's compression algorithms really can fool many to believe Ukraine is putting up fierce resistance.

The latest disinformation seems to be a seemingly staged conversation between a Ukranian driver and a Russian APC squad. I don't know who stands to benefit from these disinformation campaign but :

1) Ukranian side can raise morale by selling perception that Russia is poorly equipped and suffering from poor morale.

2) Russian side would purposefully allow such disinformation to spread for an element of surprise, might even be the one manufacturing it.

It is probably a combination of the two but from today's executive order from Putin to launch an all out offensive from all direction will be telling.

Send in the poorly equipped, inexperienced troops in first to feign false sense of security and send in your regular well equipped army.

White noise on all sides and I am noting too, just how difficult it is to get the real story but it seems Twitter makes this extra difficult and its not clear who is leaking these fake disinformation stories and to whom it is aimed to ultimately benefit.

We simply do not know what is happening but I am leaning towards #2, today's encirclement and seige of Mariupol, which was long touted as putting up effective resistance by pro-Ukraine twitter accounts, seems to have collapsed in a matter of hours, sort of like the "Ghost of Kiev" myth
