Composite armor was first introduced in soviet tanks which utilized glass reinforced Plastics layered between steel layers, resins with Boron carbide were later utilized to change viscosity and spalding of armor. Furthermore, Reactive armor was a Russian concept.
In terms of infantry fighting vehicles the Russian BMP set the standard for modern infantry fighting vehicle. Let's also no forget where the concept of a smoothbore gun came from.
So the Altay used composite armor, a smoothbore gun and presumably reactive armor which are pioneered by Russians and the Russians are the ones that are miles behind?
