the thing is Russia cant throw its full weight into the fight because its a special military operation and as such cannot ask for reserves
this is why Chechnya, Syria, Iran and North Korea are helping with men + missiles
if Russian decided to call it a war and mobilise all those Lada factories will be making T90 tanks on mass
millions of Russian troops will be in the fight and the Soviet Steam roller will crush everything and anything in its path
however things maybe about to change
if the summer belongs to Ukraine the Winter always belongs to Russia
