A Generaloberst was the second-highest general officer rank in the German Reichswehr and Wehrmacht, the Austro-Hungarian Common Army, the East German National People's Army and in their respective police services. The rank was equal to a four-star full general but below a general field marshal. The rank was equivalent to a Generaladmiral in the Kriegsmarine until 1945 or to a Flottenadmiral in the Volksmarine until 1990. It was the highest ordinary military rank and the highest military rank awarded in peacetime; the higher rank of general field marshal was awarded only in wartime by the head of state. In general, a Generaloberst had the same privileges as a general field marshal.

General admiral or Admiral general was first a Dutch then Danish, German, Russian, Portuguese, Spanish and Swedish naval rank. Its historic origin is a title high military or naval dignitaries of early modern Europe sometimes held, for example the (nominal) commander-in-chief of the Dutch Republic's navy.
