Putin is clearly worried about giving a military he doesn't trust enough toys to ride on Moscow, I suspect enough to paralyse them whilst focusing on smaller arms to try to maintain current territory is the goal.Yeah I find it weird - their reserves, repair capacity and new production combined of many armoured vehicles and artillery will also run out within about 12 months with current rates of depletion vs replacement. Yet there doesn't seem to be much hurry to ramp up industry towards military ends.
Same with their new [design] IFVs - production is so low they can't replace losses fast enough albeit they've still got loads of very old ones.
