... you do realize that between Ukraine and Russia they've lost 2,500 Russian AFVs, and 2,500 MBTs between them in that same time?   
 
Wrong.  They were relegated to mobile artillery because their gun and optics gave them a distinct advantages at 1+km engagements.
No, I'm pointing out what the world has known for years:  The T-72 is a death trap. M1 Abrams crews tend to survive even when the tank is destroyed. 
Saying that Abrams have been "humiliated" by the loss of 80 tanks over the course of the war while promoting the prowess of a tank that has suffered 2,500 losses in the same conflict is just bizarre... but you do you.
But by all means keep thinking the Russian tanks are great.  T-72s are a great way to waste valuable tank crews. 
But I'm sure Russia will roll over Ukraine any day now. 
 
It should also be pointed out that the biggest negative for the Abrams tanks in Ukraine is that they are piloted and maintained by novice Ukrainian crews.  The same can't be said for the Russian T-72 crews... what's left of them.
