Luchinsky led the 28th Army in Operation Bagration, in which it broke through German defenses in the Parichi sector and crossed the Western Bug near Brest, then fought on Polish territory. The army was withdrawn to the Reserve of the Supreme High Command in September before being transferred to the 3rd Belorussian Front in mid-October, fighting in the Gumbinnen Operation. Entering into battle from the second echelon of the front, the army broke through German border defenses and captured Stalluponen on 25 October. During the East Prussian Offensive between January and March 1945, the army broke through German defenses and reached the central part of East Prussia, reaching the Baltic coast southwest of Königsberg and encircling the German troops in the city. For his leadership of the army in the East Prussian Offensive, Luchinsky was awarded the title Hero of the Soviet Union and the Order of Lenin on 19 April. After the fall of Königsberg, the army was withdrawn to the Reserve of the Supreme High Command on 1 April and on 20 April joined the 1st Ukrainian Front, with which it ended the war in the Berlin and Prague Offensives. In the latter, the 28th, in conjunction with the 52nd Army, attacked from the Niesky area towards Zittau and Česká Lípa and approached Prague from the northeast, accepting the surrender of surrounded German troops. For "skillful command," Luchinsky received the Order of Suvorov, 1st class on 23 July 1944 and 29 May 1945 and the Order of Kutuzov, 1st class, on 16 May 1945.
