The 1077th Anti-aircraft Regiment (Russian: 1077-й зенитный артиллерийский полк, 1077-y zenitnyy artilleriyskiy polk) under Colonel Raiynin, was a unit of the Stalingrad Corps Region of the Soviet Air Defence Forces which fought during the Battle of Stalingrad in 1942. The Stalingrad Corps Region was part of the Stalingrad Military District and later subordinated to the Stalingrad Front during the battle for the city. The regiment, like many of the anti-aircraft units, was made up almost entirely of teenage female volunteers, barely out of high school. They are mostly known for their bravery in the defense of Stalingrad (now Volgograd), when they engaged an advancing Panzer unit by setting their guns to the lowest elevation and firing them directly at the advancing tanks.
