If it hit the strongest part of the turret armour, then yeah it would stop it from penetrating.
I’m fairly sure a shot to the turret ring would cripple an abrams. Despite it being weaker/larger than IRL it still is theoretically a place you can penetrate with modern APFSDS.
In reality it’d be virtually impossible as with 125mm APFSDS penetrators you’d have to aim within ~5mm in order to actually hit the turret ring. What they showed in the trailer was a shot from below, with the SEP’s barrel aimed slightly upwards for some reason, and the gap that the T-90M had to aim for was still likely at most a few inches tall.
War Thunder is really has been improving on their updates and trailers for every new season. I really would love for them to keep up their great work! They probably own the best game I’ve ever played in my life. Great Work to Gaijin Entertainment and to their staff!
