The Ukrainian air assault forces finally have deployed their most powerful unit. The 2,000-person 82nd Air Assault Brigade, which is stacked with Marder and Stryker fighting vehicles and Challenger 2 tanks, rolled into action around Robotyne, in southern Ukraine’s Zaporizhzhia Oblast, apparently in the last few days. The deployment is good and bad news for Kyiv’s long-anticipated counteroffensive, which kicked off with a series of coordinated assaults across southern and eastern Ukraine starting on June 4.
