Spring Counteroffensive Looms in Russia-Ukraine War.

Ukraine's Challenger 2 tanks and Russia's reactivated T-55 tanks could potentially meet in combat. The last time they clashed was in 2003 during the Iraq War, resulting in a lopsided victory for the Challenger 2. The T-55 is no more effective now than it was in 2003 or 1973, and there is no reason to expect a different outcome if they meet in Ukraine.
