Russian media outlet RIA Novosti has cited a study which says the majority of the 31 US-supplied M1 Abrams tanks delivered to Ukraine have been destroyed.

The tanks, which were authorized for transfer under President Biden, have all been destroyed or damaged with the exception of a mere five. These remaining tanks were then reportedly pulled from the front lines given Ukrainian commanders’ fears they are too vulnerable to superior Russian airpower. The claim that 26 have been destroyed since they entered the battlefield seems plausible, and consistent with an April 2024 Associated Press report which confirmed at the time, “Ukraine has sidelined U.S.-provided Abrams M1A1 battle tanks for now in its fight against Russia, in part because Russian drone warfare has made it too difficult for them to operate without detection or coming under attack,” citing two US military officials.
