In February 1944, his regiment was withdrawn from the front and converted into the 395th Guards Heavy Self-Propelled Artillery Regiment. It was also reequipped with the updated ISU-152 self-propelled gun, one of which Snetkov became commander of. Snetkov and his regiment did not return to the front until June 1944, where they became part of the 3rd Belorussian Front. He was promoted to lieutenant around this time, and from late June, he fought in Operation Bagration, the Soviet strategic offensive that recaptured Belarus and eastern Poland. Between 22 and 27 June, during fighting in the Bogushevsk area, Snetkov's crew was reported by a superior to have destroyed a self-propelled gun, two bunkers, and two anti-tank guns. For this he received a second Order of the Red Star on 10 July. The regiment, as part of the front, fought in the Baltic Offensive and the Gumbinnen Operation during the fall.
