“The media is reporting that they are T-72s, by the way.”
The “media” is largely proven to know very little about arms.
Wouldn’t a T-72 have a large flash suppressor?
Tanks don't have flash suppressors. The thing seen at the end of some tank barrels is a muzzle brake which reduces the recoil of the main gun. The other thing is a bore evacuator which prevents noxious gases from entering the crew compartment when they open the breech to reload the gun.
