The first airborne forces parachute jump is dated to 2 August 1930, taking place in the Moscow Military District. Airborne landing detachments were established after the initial 1930 experimental jump, but creation of larger units had to wait until 1932–33. On 11 December 1932, a Revolutionary Military Council order established an airborne brigade from the existing detachment in the Leningrad Military District. To implement the order, a directive of the Commissariat of Military and Naval Affairs transformed the Leningrad Military District's 3rd Motorised Airborne Landing Detachment into the 3rd Airborne Brigade (Special Purpose) commanded by M.V. Boytsov. Two further airborne brigades (the 13th and 47th) and three airborne regiments (the 1st, 2nd, and 5th, all in the Far East) were created in 1936. In March and April 1941, five Airborne Corps (divisions) were established on the basis of the existing 201st, 204th, 211th, 212th, and 214th Airborne Brigades. The number of Airborne Corps rose from five to ten in late 1941, but then all the airborne corps were converted into "Guards" Rifle Divisions in the northern hemisphere summer of 1942.
