1st Belorussian Front
The 1st Belorussian Front (, Pervyy Belorusskiy front, also romanized "Byelorussian") was a major formation of the Soviet Army during World War II, being equivalent to a Western army group. The 1st Belorussian Front along with the 1st Ukrainian Front were the largest and most powerful among all Soviet fronts, as their main effort was to advance on the Nazi German capital Berlin. Creation and initial operations 
Initially, the Belorussian Front was created on 20 October 1943 as the new designation of the existing Central Front. It was placed under the command of General Konstantin K. Rokossovsky, who had been commanding the Central Front. It launched the Gomel-Rechitsa Offensive in 1943 and then the Kalinkovichi-Mozyr Offensive in 1944. Redesignation and 1944 operations 
It was then renamed the 1st Belorussian Front (1BF) on 17 February 1944 following the Dnieper–Carpathian Offensive. A few days later, on 21 February, the Rogachev-Zhlobin Offensive commenced, which continued until 26 February. The next operation was the Bobruysk Offensive, part of Operation Bagration, and on 26 June the attacks of 1BF encircled Bobruisk, trapping 40,000 troops of the German 41st Panzer Corps (part of 9th Army). From 18 July-2 August the Front was part of the Lublin-Brest Offensive. From 2 August to 30 September, the Front was engaged cleaning out Germans to the east of the Vistula (during which the Battle of Radzymin took place from 1–10 August). Its 8th Guards, 28th, 47th, 65th, 69th, and 70th Armies were involved at Radzymin. Later during that same period, on 14 September, 1BF with the support of Polish forces it captured Praga, a suburb of Warsaw. Operations in 1945
The next attack was the Warsaw-Poznań Operation, a part of the Vistula-Oder Offensive. On 13 January, 1BF began an offensive toward Pillkallen (Schlossberg between 1938 and 1945) in East Prussia, against which they met stiff resistance from the 3rd Panzer Army. The 1st Belorussian Front opened its attack on the German Ninth Army from the Magnuszew and Puławy bridgeheads at 08:30 on 14 January, again commencing with a heavy bombardment. The 33rd and 69th Armies broke out of the Puławy bridgehead to a depth of 30 km, while the 5th Shock and 8th Guards Armies broke out of the Magnuszew bridgehead. The 2nd and 1st Guards Tank Armies were committed after them to exploit the breach. On 25 January, the Front cut off the fortress city of Poznań which held 66,000 Germans, and continued its 80 km a day advance, leaving the 8th Guards Army to lay siege to the city, which they finally took on 23 February. Capture of Berlin
Along with the 1st Ukrainian Front, 1BF then stormed Berlin in the climactic Battle of Berlin. Marshal Georgy Zhukov was appointed commander of the 1BF, in November 1944, for its last two great offensives of World War II. After the capture of Poland and East Prussia (its capture was finished on 25 April with capture of Pillau) from January–March 1945, the Soviets redeployed their forces during the first two weeks of April. Marshal Georgy Zhukov concentrated 1BF, which had been deployed along the Oder river from Frankfurt in the south to the Baltic, into an area in front of the Seelow Heights. The 2nd Belorussian Front moved into the positions being vacated by the 1BF north of the Seelow Heights. While this redeployment was in progress gaps were left in the lines and the remnants of the German II Army which had been bottled up in a pocket near Danzig managed to escape across the Oder. In the early hours of 16 April the Berlin Offensive Operation started with the objectives of capturing Berlin and linking up with Western Allied forces on the Elbe. The operation started with an assault on the Seelow Heights by 1BF and by Marshal Konev's 1st Ukrainian Front (1UF) to the south. Initially the 1BF had great difficulty smashing through the German lines of defence, but after three days they had broken through and were approaching the outskirts of Berlin. By 22 April 1BF had penetrated the northern and eastern suburbs of Berlin. They finished the encirclement of Berlin on 25 April when units of the 1BF and 1UF met at Kietzen west of Berlin. After heavy street by street and house to house fighting, General Weidling, the commander of Berlin's garrison, met with Marshal Chuikov and surrendered Berlin unconditionally at 15:00 hours local time on 2 May. Post-war
On 8 May, after a signing ceremony in Berlin, the German armed forces surrendered to the Allies unconditionally and the war in Europe was over. Following the war, the Front headquarters formed the Group of Soviet Forces in Germany. Commanders 
The Front's Commissars included
Lt. General Konstantin F. Telegin [continuing from Central Front] (October 1943 – May 1944; November 1944 – June 1945)
