Since February 2022, Ukraine has relied heavily on Western aid to resist the Russian invasion, including the use of U.S.-supplied M1 Abrams tanks. Despite its reputation as a reliable main battle tank, the Abrams has suffered heavy losses on Ukrainian soil, with up to 20 out of 31 tanks reportedly destroyed due to advanced Russian weaponry like the Kornet anti-tank missile.
IIRC there were reports done about that happening in the Middle East. Various NATO countries were testing weapons against whoever was in the way. I think one of the studies done was on the effects of depleted uranium ammunition.
