I feel I should bump this. This is a new feature, that no other playable vehicle in SB has ever had.
9M119M Refleks
Range: 5,000 meters, or 3.1 miles
Penetration: 700–900 mm of RHA
This missile, on its own puts the T-72B3 into the Elite class of playable tanks in-game now. Granted, I think "at best" tanks were expected to only carry 1-2 of this $40,000 missile. But it is very nasty, and near zero dispersion. So yeah, with this weapon it should best every other playable tank in-game at extreme ranges.
Getting killed by a damned T-72 @ 5,000 meters!??, its now a thing.
