The General Staff was divided between the central "Großer Generalstab" in Berlin and the general staffs of the corps and division HQs. The head of the "Großer Generalstab" was the "Chief of the General Staff" and was also the technical superior of all general staff officers. The Chief of the General Staff's chief deputy held the title of "Generalquartiermeister". Beneath them were the five "Oberquartiermeisters", who supervised the heads of the General Staff departments. The Railroad Department had the largest number of officers assigned, while the Second Department was the most important.
