After recovering, Dubovoy became commander of the 16th Tank Corps, being made a Hero of the Soviet Union for his leadership of it in the Uman–Botoșani Offensive of early 1944.

In September 1920, after the defeat of the Red Army in the Battle of Warsaw, Dubovoy was interned in East Prussia with the 2nd Battery of the 12th Separate Heavy Field Artillery Battalion,[2] returning to Soviet Russia a month later.

From October 1937, he served as assistant chief of the 1st department of the Tank Directorate of the staff of the Special Red Banner Far Eastern Army.

He was appointed chief of staff of the 25th Tank Brigade, forming at Novoye Sormovo, on 29 September, which was sent to the Western Front as part of the 5th Army in the second half of October.

The brigade was subsequently relocated to Istra, and Dubovoy took command of it on 31 October, during the Battle of Moscow, in which the 25th fought in the Solnechnogorsk area.

The brigade was withdrawn to the Reserve of the Supreme High Command on 18 December and in February 1942 he was appointed deputy commander-in-chief for tank forces of the 47th Army of the Crimean Front, and in late May became chief of staff of the 27th Tank Corps (converted into the 1st Mechanized Corps in September), fighting on the Kalinin and Steppe Fronts.

[3][2][4][5] Dubovoy distinguished himself in during the capture of the city of Pyatikhatka on 19 October 1943 during the Battle of the Dnieper but was severely wounded a few days later near Krivoy Rog.

[2] For his "courage and heroism" during the attack of his corps upon the Axis flank and rear on the outskirts of Uman during the Uman–Botoșani Offensive in spring 1944, Dubovoy was made a Hero of the Soviet Union and awarded the Order of Lenin on 11 March.

In August, Dubovoy was recalled from the front and appointed head of the Higher Officers' School of Self-Propelled Artillery of the Red Army Armored and Mechanized Forces.
