“New prototype Russian IFV?
Previously unseen heavy Russian APC/IFV based on what appears to be and sounds like a T-90 tank chassis that was filmed at the Nizhny Tagil Uralvagonzavod factory training ground.
I think they are tired of blowing up all the time and are looking to develop something like the Bradley IFV. “

“New prototype Russian IFV?”
Perhaps they use the T-90 chasis because they have the tooling and capability to produce them (and the support tail would be common as well).
I think that T-90s are the only tanks they really produce nowadays, and only 100-200 per year.
Putting a smaller IFV-type cannon on it would allow a lot more smaller rounds to be carried on board, so shots could (theoretically) be spread over many more smaller targets, like fighting positions, during a rapid assault. In practice, it takes fire discipline to not just keep firing, in the heat of the moment. If nothing else, you can adjust fire more rapidly, than having to reload another big tank round.
The higher rate of fire from IFV cannons is more suppressive of enemy fire, while the destructive impact of tank main gun rounds is more reliably effective in neutralizing targets.
There are a lot of reasons to team them together in practice. The difference between American Armored (Tank) and Mechanized units in design, is the relative mix of the vehicle type.
Since they travel and fight together, it is a great idea to have as much commonality in spare parts and special tools required to sustain them, as possible.
