The brigade traces its lineage back to the formation of the 66th Anti-Aircraft Artillery Division (Russian: 66-я зенитная артиллерийская дивизия) in October 1943 during World War II.

In 1973 the regiment was expanded into the 140th Anti-Aircraft Missile Brigade, deploying to Trzebień in Poland as part of the Northern Group of Forces.

On 30 June, during Operation Bagration, the Soviet strategic offensive into western Belarus and eastern Poland, the division reached the Berezina River following a rapid advance by the 31st Army.

It was further relocated to Dagestan by 2 November, stationed in the area of Izberg and Dvigatelstroy as part of the reserve of the Transcaucasian Military District.
