While a lot of tanks share similarities in how to operate them, learning a foreign tank's systems and operations is a tall task. You can't just take a bunch of Ukrainians who drive Soviet style tanks and stick them in an M1 Abrams and expect them to operate it effectively. It takes at least several weeks to familiarize one with how it handles, what it is capable of, the large variety of weapon systems, it's defensive capability, and so on. So, while they're training to use these new tanks... the Russians can just advance without worrying about having to engage them? Or, they give Ukrainian crews a retarded crash course, and send them out there wildly unprepared. Russian tanks are certainly a match for the M1 Abrams, especially if their crews are more proficient than the Ukrainian crews. Expect to see a shit load of M1 Abrams getting tagged with ATGMs and AP rounds from other tanks. Over on watchpeopledie.tv there is a ton of combat footage from the Ukraine war (as well as like 20 other wars ongoing right now)- a lot of it is GoPro or drone camera, very clear and detailed footage. Most of them are fucking drone's dropping little grenades on unsuspecting infantry. I'm wondering when a good countermeasure will be devised to deal with these little fucking things, they're worse than snipers IMO- at least the sniper has to be in some danger to take a shot. The faggots piloting these little drones are likely a dozen km or more away from where the action is happening, so they can be calm and carefully line up their bomb drop without fear of being shot at and killed. Drones are the new terror weapon of modern combat.
