The vehicle is an SU-85, which is not air transportable. The ASU-57 was the air transportable one.
“The BMD-4 features an advanced fire control system (FCS). The unique armament system provided by the Bakhcha-U and the reliable ride performance provided by the chassis gives the BMD-4 qualitatively new capabilities to units of land forces. The BMD-4 is able to fire all its primary armaments effectively regardless of whether the vehicle is stationary or mobile, whether the time is day or night, or whether it is afloat or land based. The FCS implements a significant increase of the armament effectiveness by engaging a wide scope of targets in complicated weather and landscape conditions. Advanced ballistic calculations allow the BMD-4 to fire from an enclosed position and the capability of effectively firing at low and slow aerial targets is provided.”

“the BMD-4 is capable of parachuting from aircraft with the entire crew and passengers inside the vehicle which allows target engagement after landing to be instant. An Il-76 is able to transport two of these vehicles at a time in comparison to three BMD-1s and BMD-2s.”
I have no idea how useful it really is nowadays given what Ukrainians use against armored vehicles.
The ASU-85 (Russian: Авиадесантная самоходная установка, АСУ-85, romanized: Aviadesantnaya Samokhodnaya Ustanovka, ASU-85 – airborne self-propelled mount) is a Soviet-designed airborne self-propelled gun of the Cold War era. From 1959, it began to replace the open-topped ASU-57 in service.[2] It was, in turn, replaced by the BMD-1 beginning in 1969.
