In terms of actual combat effectiveness of tanks, Russia is indeed generally behind the mainstream European countries at present.
There's not much that can be done about this, as the wariness and blockade of Russia by the European countries is understandable, explaining why Russian tank development has always been so slow.
Moreover, prior to this, the industrial foundation of Tsarist Russia compared to other powers was relatively weak, with poor research and development capabilities for equipment, and frequent skimping on research funds and incidents of substituting inferior goods for good ones.
Under such circumstances, that Russia has managed to develop tanks and mechanized equipment that can actually be used on the battlefield is already quite an achievement.
The Defense Industrial Administration of Russia, the organization that developed the armored troops, was only established in 1924, which is just 13 years ago.
