Indeed. We'll find out how vulnerable this particular tank is to that weapon - which seems to be designed for ground-level launch (up, loop over, straight down). The big question is whether they've sufficiently improved top protection.

This tank is specifically for urban warfare. In that environment, maneuverability is somewhat constrained, I'd expect that a tank there would be much more vulnerable to an artillery barrage than a tank in open territory.

There's been nothing like the Javelin, nor the UA's now-upgraded artillery on the opposing side in Chechnya and Syria. So it's an unknown. Given the RF's lack of speed in upgrading weapons, I would guess it isn't going to go any better for them than with the T72 variants.
