In August 1943, Lieutenant Motsny was appointed commander of a platoon of T-34 tanks in the 54th Guards Tank Brigade on the Voronezh Front until the end of the war. On 28 August, he was lightly wounded and soon returned to his unit. Until October 1943, the brigade took part in battles in Ukraine. From 4-11 November, 1943, Motsny took part in the liberation of Kiev. On 6 November, 1943, Motsny, on his tank, managed to destroy up to 100 enemy carts with military cargo and property, ten vehicles, and about 100 German soldiers and officers retreating from Kiev. In battle, Motsny's tank was knocked out by a Tiger I, but the tank's crew was able to capture a communications vehicle with six radio stations and five guns in battle. When the retreating column was utterly defeated, Motsny's tank was withdrawn from the battlefield for repairs. For this battle, the battalion commander presented Motsny and the driver of his tank, Morozov, the rank of Hero of the Soviet Union. However, the award was reduced by higher commanders, and as a result, they were awarded the Order of the Red Banner.
