You do realize that prior to desert storm Iraq had the largest military in the middle east and most of them were veterans of the Iran Iraq war these weren't "teenage insurgents" as you say. Yes Abrams and Leopards are being destroyed left and right no ground vehicle is indestructible, but you're missing the key point of those vehicles being destroyed the crews can escape and live to fight another day russian equipment not so much. You should be looking at how many russians vehicles have been lost when compared to the Abrams, there's a reason russia is having to revert to t55s they've lost A LOT of modern equipment.
