Or does Russia use Chinese tech?
Russian is top down innovation with a thick layer of corruption. No matter how much you want to claim strategic depth, they are always several steps behind Ukrainians. No matter how many advantages due to size they have.
Sorry you picked the wrong team.
I'm talking about mass manufacturing, not design. Russia has had capability to hit any Ukrainian factory since Day 1 of the war, that's why they've successfully dispersed and hidden their production so much. Also, I've always been pro-Ukraine.
>they are always several steps behind Ukrainians.
That's not true anymore, both sides have plateaued because all innovations are quickly copied. Anti-recon quadcopters were another Ukrainian innovation that took the Russians roughly 6 months to catch up to. The only advantage they have is size and strategic depth. There isn't much else.
