US-made Abrams are better than Russia's best tanks in the war, Ukrainian commander says, and it's not even close

• A Ukrainian M1 Abrams commander said the American tank is better than Russia's best in this war.
• He said the Abrams is better than Soviet tanks and even the T-90 that Moscow has deployed.
• Putin touted the T-90M specifically as the "world's best tank."

Ukraine is operating a small fleet of US-made Abrams tanks, combat-proven vehicles that were built to destroy Russian armor.
