Ever wondered why Gaijin added those stupid ASU-57 and ASU-85 tanks that are clearly post-war vehicles (with post-war ammo), but not in tier 5?
Maybe they thought of adding something like this:
Note how at the 2:00 mark they show how the Russian airborne tanks were landed - with brake rockets igniting few metres above ground.
Supposedly, Russian airborne troops stay in such vehicles during the airborne operation (at least on combat drops)!
