Generaloberst (en: colonel general) was, in the German Reich, the Reichswehr, Wehrmacht and the Austria-Hungary Common Army, the second highest general officer rank comparable to the then four-star rank in many NATO-Armed forces (Rangcode OF-9). In armed forces, structured in line to the former Soviet Army or the today's Russian Army, today it is a Three-star rank (OF-8). It was equivalent to Generaladmiral in the Kriegsmarine until 1945, or to Flottenadmiral in the Volksmarine until 1990.
A supreme general or senior general (Generaloberst, often translated as "colonel-general" by analogy to Oberst, "colonel." However, since "Oberst" derives from the superlative form of "Ober" meaning "Above" then "Superior General" might be a more idiomatic rendering.) was the second highest general officer rank—below field marshal (Generalfeldmarschall)—in the Prussian army as well as in the Deutsches Heer of Imperial Germany (1871-1919), the Reichswehr of the Weimar Republic (1921-1933), and the Wehrmacht (which included the Luftwaffe, established in 1935) of Nazi Germany (1933-1945). It was generally reckoned as the equivalent of a full four-star general in the American and British armies.
