BMPT "Terminator". Despite the name, it is derived from a T-72 chassis. Twin 30mm auocannon, co-ax 7.62, quad AT-9 tubes, and a pair of 30mm grenade launchers. Designed to fight infantry in urban areas, after experiences in Chechnya where Shilkas were pressed into the role and found not quite up to the task.
Tank platoon in Chechnya; the furthest one may actually be a Shilka, not sure, but the old SPAAGs struggled away at providing close support to the tanks in Chechnya. Shilkas, like all SPAAGs are clumsy and weak in close support roles; loads of firepower but not particularly great awareness or armour.
In a pinch, however, armies still use them this way.
Such as in Syria.
The BMPT packs on even more hull armour than the T72 and T90 tanks it's derrived from, with high-angle gun system and lots of optics for spotting trouble around it. There is nowhere the tanks can go that this thing can't follow.
Unrelated freeby, since i'm busily dodging ye olde "double post rule".
