A Generaloberst ("colonel general") 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 Generalfeldmarschall. 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.
A literal translation of Generaloberst would be "uppermost general", but it is often translated as "colonel-general" by analogy to Oberst, "colonel", such as in countries in which the rank was adopted like Russia (Russian: генерал-полковник, romanized: general-polkovnik). "Oberst" derives from the superlative form of Germanic ober (upper), cognate to English over and so "superior general" might be a more idiomatic rendering.
