Most military academies and cadet schools, as well as a number of HQ and support units of military formations and commands, maintain a corps of drums (known locally as rota barabanshchiki) that are specifically brought out during military parades. These formations too are of Imperial origin. Corps of drums are always made a separate part of military bands and are usually led by a drum major in the place of the director of music of a certain band and are the first formation to march past the saluting grandstand in parades, with its drummers first sounding a drumbeat cadence that keeps the parade on the beat before they march past. If possible, the corps of drums of the local Suvorov or Nakhimov Naval School would be used during events of national importance. The most famous of these special units in the international sphere would be the Corps of Drums of the Valery Khalilov Moscow Military Music College, first unveiled during the Moscow Victory Parade of 1945 and has since been regular participant in the October Revolution Day (1938 to 1990), May Day (1938 to 1968) and Victory Day (1965, 1985, 1990, 1995–2008, 2012-) parades on Red Square. A Turkish crescent for the college was used as its unit symbol during the Soviet era until it was replaced in 1995 by a colour guard squad. Most of these corps have an instrumentation that includes snare drums, fifes, trumpets, glockenspiels and on occasion, chromatic fanfare trumpets and trombones, and its musicians wear the service or full dress uniform of their respective unit or educational institution. Until 1969 the corps of drums, following its march past in front of the parade grandstand, would be positioned near the massed bands to provide additional support in parades. It has been resumed only in Moscow beginning in 2010, but only on Victory Day during the mobile column segment.
