M1A2 after hit in front hull smoking from turret

I don't see any smoke coming from the turret hatches once the dust and explosion smoke are cleared, nor there is any picture of the aftermath to show what happened to that vehicle.
For all that we know it it may not even have immobilized it. There is simply not enough info to make a call and given it is propaganda the proverbial pinch of salts need to apply.

soviet anti-tank gun MT-12R not have right data. This gun have radar FC system

There has been a fair amount of debate about the radar unit on the MT-12 being little more than an all weather radar rangefinder or being actually useful for target acquisition as well. If the source is correct then it is a capable and likely cost effective system, though I would suspect that target classification would leave something to be desired compared to a thermal sight.

6) in game is abscent total soviet 100mm AA gun
7) in game is abscent total soviet 130mm AA gun

As a policy heavy antiaircraft guns like the above are not present in the game as anti-air units. The only ones available, such as 85mm KS-12 in some OOBs, are classed as antitank guns.
This because in the anti-air mode they would be used to shoot at level bombers, which are used very sparingly in the game.
If you check the the others OOB you will see the various 90mm, 3.7 Inch QF etc. aren't available either.

About MT-12R - it's site developers gun radar. And about classification - not need. Smoking forward gun smoke with not see visual and thermal and fire through smoke in all targets what was find.
About 100mm and 130mm AA guns - I understand.
About M1A2 - I not hope see anyone other. All like western propaganda and refuse facts... as usually.
