Grigorii Rabinovich was born in 1922 in the village of Rokytne, south of Kiev, in Ukraine. His father was a tailor. Grigorii graduated from a ten-year school in 1941 and expected to be drafted. In June 1941, the Soviet-German war began. Rabinovich recalled that many Ukrainian peasants did not conceal their joy at the German attack on the Soviet Union and did not want to fight. He received a call up for military service in July 1941 and, together with 80 other draftees, was taken on foot eastward. On the way most of the Ukrainian conscripts deserted so that when their column arrived in Poltava, in eastern Ukraine, it consisted only of Jews and Ukrainian sons of Party and Soviet officials. Eventually, the draftees arrived in Bashkiria, in the Urals, where they underwent military training.
Grigorii's frontline experience began in July 1942 in the North Caucasus. He was caught up in steady retreat of the Red Army from Rostov-on-Don to Stalingrad on the Volga River, almost without any clashes with the enemy. Grigorii took part in the Stalingrad operation between the fall of 1942 and the winter of 1943. Then until 1945 he took part in the Red Army offensive in the Upper Don area, then in the Kharkov operation, which was a disaster for the Red Army. Subsequently, he fought in Ukraine, Romania, Hungary, and Austria. He recalled the Budapest operation of 1944-1945 as the most terrible one he experienced, even more terrible than Stalingrad and Kharkov.
In Ukraine Rabinovich's division was reinforced by Ukrainians who were not drafted in 1941 or had escaped earlier recruitment. Rabinovich noted that those people, who had lived under the German occupation between 1941 and 1943, introduced considerable antisemitism into the ranks of the Red Army. He also recalled discrimination against Jews in the granting of military awards.
Grigorii Rabinovich met VE-Day in the mountains of Austria. Since neither the German nor the Soviet forces there knew that the war had ended, fighting in this area stopped only on May 11. On that day his unit met U.S. military units, with which a joint victory celebration was organized. After that, Grigorii's unit was transferred to western Ukraine to fight the Ukrainian Insurgent Army – an anti-Soviet nationalist military formation that refused to lay down its weapons in 1945. Rabinovich was released from military service only in November 1946.
After the war Rabinovich worked as an economist.
