A video has emerged showing, apparently for the first time, a U.S.-supplied M1 Abrams tank in action on the front lines of Ukraine. While it’s been known that these tanks have been in the country since at least last September, the appearance of a Ukrainian Abrams reportedly close to Avdiivka in the eastern Donetsk region — as well as possible evidence of one having been put out of action — confirms that these capable combat vehicles are indeed in the fight.The video in question began to circulate on social media today. Taken from a series of drones, it shows a single Ukrainian M1 moving along roads through a snowy landscape, full of shell holes and shattered trees. In several parts of the video, the tank is seen opening fire against Russian positions, with distinctive muzzle blasts and large explosions. These portions of the footage are of noticeably worse quality, but the background does seem to be the same as that where we also see the Abrams underway.The video seems to have been produced by the Ukrainian Ground Forces’ 47th Separate Mechanized Brigade, a unit known to have seen plentiful action in the fierce fighting for Avdiivka and which had been previously known to operate Leopard 2A6 tanks. Specifically, it’s been said that the video shows an M1 engaging Russian positions in Stepove, but this cannot be confirmed.
