It was also used in the East German National People's Army from 1956 to 1990.
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.
By the GDR National People's Army and the Border Troops the rank was introduced in 1962, comparable to NATO OR-6a.
