() was a rank of the Wehrmacht from 1935 until 1945. It was also used in the East German National People's Army from 1956 to 1990. The equivalent to Unterfeldwebel in the Bundeswehr of West Germany and later the Federal Republic of Germany is the rank Stabsunteroffizier (OR-5).
History Unterfeldwebel (in Cavalry, Artillery, and Armoured corps: Unterwachtmeister) was in Germany the designation to a person in uniform with the second lowest NCO-rank (after Unteroffizier). It was counted to the rank-group Unteroffiziere ohne Portepee.
The rank-designations Unterfeldwebel, respectively Unterfeldwebel were created by renaming of the Sergeant rank of the Imperial German Army
Independent to the military assignment an Unteroffizier could be promoted to Unterfeldwebel after a service time of three to four years. Since 1936 this rank could normally be skipped in Heer and Luftwaffe, and NCOs with the rank Unteroffizier were promoted to Feldwebel.
