This is the Russian Red Army Choir. The Red Army Choir (Choir Aleksandrov) is a performing ensemble that served as the official army choir of the former Soviet Union's Red Army. In the late Soviet Union its full name was Дважды Краснознамённый ордена Красной Звезды академический ансамбль песни и пляски Советской армии имени А.В.Александрова, which may be sensibly translated as "the Academic Ensemble of Song and Dance of the Soviet Army, Bearer of Two Orders of the Red Banner and the Order of the Red Star named after Alexandrov".
