Structure of the 1st Czechoslovak Army Corps
The 1st Czechoslovak Army Corps was redesignated the 1st Czechoslovak Army.
 - Commander – Marshal I.S. Konev.
 - Commander – Colonel General K.S. Moskalenko.
 - Commander – Army General I.E. Petrov.
 - Commander – Colonel General A.A. Grechko.
 - Commander – General A. I. Gastilovich.
 - The Soviets had attributed the high Czechoslovak losses in the first days of the Carpatho-Dukla operation to Brigadier General Kratochvíl’s perceived poor performance. They named Brigadier General Svoboda the new corps commander even though such assignments were the sole prerogative of the Czechoslovak President.
 - General Klapálek (formerly commander of the 3rd Cs. Independent Brigade) relieved Brigadier General Svoboda, who became the Minister of National Defense.
 - As of 09/1944. This number included the reserve regiment and rear echelon units. Beginning in 08.09.1944, about 13,000 personnel were combat personnel.
