from the same area as X. Armeekorps. However, these links between rear areas and front line units were broken as the war went on and later corps were raised with troops from all over Germany. Division The basic tactical formation was the division. A standard Imperial German division was organized into: Division HQ two infantry brigades organized into a brigade HQ and two regiments each (either of the line or light infantry), a cavalry brigade organized into a brigade HQ and two regiments an artillery brigade organized into an HQ and two regiments Combat service and support regiments under division HQ One of the divisions in a corps area usually also managed the corps region ().

As World War I progressed, additional divisions were formed, and by wars' end, 251 divisions had been formed or reformed in the German Army's structure. Regiment The regiment was the basic combat unit as well as the recruiting base for soldiers. When inducted, a soldier entered a regiment, usually through its replacement or training battalion, and received his basic training. There were three basic types of regiment: infantry, cavalry and artillery. Other specialties, such as pioneers (combat engineers) and signal troops, were organized into smaller support units. Regiments also carried the traditions of the army, in many cases stretching back into the 17th and 18th centuries. After World War I, regimental traditions were carried forward in the and its successor, the , but the chain of tradition was broken in 1945 as West German and East German units did not carry forward pre-1945 traditions. Each Imperial German regiment of infantry had headquarters units, three battalions and one training battalion assigned to the regimental depot.
