In Operation Desert Storm, western tanks proved very effective versus Soviet built tanks. I have heard that one of the contributing factors to the massive defeat the Iraqi tanks was poor training, tactics, and old equipment. Hypothetically, how would a tank such as an Abrams, Challenger 2, or Leopard fare against a Russian T-72 that was firing anti-tank missiles out of its cannon instead of shells? My understanding is that the anti-tank missiles have a very long range and would be able to destroy a western tank. What about if it was a T-80 or T-90? I am making an assumption here that Russian tanks are equiped with better targeting and sighting systems than Iraqi tanks were. As well as better training and tactics. If this is incorrect, please let me know. Overall, I am curious how western armies would handle the Russian military if they were sent into Ukraine.
