Komandarm 1st rank (Russian: командарм 1-го ранга) is the abbreviation to commanding officer of the army 1st class (Russian: командующий армией 1-го ранга, romanized: komanduyushchiy armiyey 1-go ranga; lit.

It was also the designation to military personnel appointed to command an army group or front sized formation (XXXXX).

It was equivalent to Komissar army 1st rank (ru: армейский комиссар 1-ого ранга) of the political staff in all military branches, Fleet Flag Officer 1st rank (ru: флагман флота 1-ого ранга) in the Soviet navy, or to Komissar of state security 1st rank (ru: комиссар государственной безопасности 1-ого ранга).

However, an alternative rank structure was introduced by disposal of the Central Executive Committee of the Soviet Union and the Council of People's Commissars, from September 22, 1935.

Especially the collar insignia had to be worn out, and were finally replaced by the introduction of gorged embroidery for general officers.
