control on 1 March. The Special Military District headquarters was reorganized into the 11th Guards Army headquarters. In January 1956 the territory of the Estonian SSR was transferred from the Leningrad Military District. Circa 1944 a headquarters for Internal Troops in the area was created, which became HQ Internal Troops NKVD-MVD-MGB Baltic MD (Управление ВВ НКВД-МВД-МГБ Прибалтийского округа). This headquarters supervised several Internal Troops divisions, including the 14th Railway Facilities Protection Division NKVD from 1944 to 1951. Other divisions deployed included the 4th, 5th, and 63rd Rifle Divisions NKVD. On 30 April 1948 10th Guards Army became 4th Guards Rifle Corps. The main combat formation within the District was the 11th Guards Army in the Kaliningrad Oblast, following the disbandment of 10th Guards Army. In the 1950s it comprised the 1st TD (former Tank Corps) and all the remaining Guards formations - 2nd Rifle Corps, 16th Koenigsberg Red Banner Rifle Corps (the 1st and 26th RD, 29 MD) and 36th Nemanskiy Red Banner Rifle Corps (5th and 16th RD, 30th MD). In 1955 the district's forces comprised the 11th Guards Army, the 2nd Guards Rifle Corps, the 4th Guards Rifle Corps, the 1st Guards Rifle Division, the 5th, the 16th Guards, the 26th Guards, the 28th and 42nd Rifle Divisions, the 1st Tank Division, the 28th Guards, 29th Guards, and 30th Guards Mechanised Divisions, and the 15th Guards Airborne Corps (76th Guards Air Assault Division and 104th Guards Airborne Division). In 1955 4th Guards Army Corps consisted of 8th Guards Rifle Division (Haapsalu, Estonian SSR); 118th Guards Rifle Division (Tallinn, Estonian SSR); 36th Guards Mechanised Division (Klooga, Estonian SSR); and the 2nd Machine-Gun Artillery Division (Saaremaa Island, Estonian SSR). However, in July 1956 the 118th Guards Rifle Division was disbanded. For the entire postwar period the 11th Guards Army comprised the 40th Guards Tank Division (former 2nd Guards Cavalry Corps, then 28th Guards Mechanised Division) and the 1st Tank, and the 1st and 26th Guards MRD (former Rifle Divisions). In 1960 the 5th Guards MRD, a former Rifle Division, was disbanded. With the transfer of the Estonian area to the Leningrad Military District the 2nd Guards 'Tatsin' Tank Division went with it, leaving the District with only the 1st 'Insterburg' Tank Division in Kaliningrad, which had been reorganised from the 1st Guards Tank Corps in the later part of 1945.
