Generalfeldmarschall (German: [ɡenəʁaːlˈfɛltmaʁʃal] ; from Old High German marahscalc, "marshal, stable master, groom"; English: general field marshal, field marshal general, or field marshal; often abbreviated to Feldmarschall) was a rank in the armies of several German states and the Holy Roman Empire, (Reichsgeneralfeldmarschall); in the Habsburg monarchy, the Austrian Empire and Austria-Hungary, the rank Feldmarschall was used. The rank was the equivalent to Großadmiral (English: Grand Admiral) in the Kaiserliche Marine and Kriegsmarine, a five-star rank, comparable to OF-10 in today's NATO naval forces.
