With manuals and regulations now in place (even if under constant revision from this new base), the
Truppenamt set about reshaping the new army to fit its treaty constraints and its new doctrinal approach. The "
triangular" infantry division replaced the "
square division", with no
brigade-level staff and with three
regiments instead of four. Numbers in support forces such as artillery, reconnaissance, transport, and signals all increased, with control in many cases pushed down the organisation. All of this related to the new
"war of movement" doctrine that had been adopted. The
Wehrmacht infantry division in 1939 showed very few changes from the patterns outlined in 1921. The cavalry division was similarly reinforced with support arms and armoured cars, making it capable of independent operations deep behind enemy lines. The
Truppenamt turned some of the Versailles limitations into advantages. The very limited number of officers forced it to rethink the roles at headquarters, and this dovetailed with the doctrine of decision at the front by those who can see the enemy. Correspondingly, despite a Versailles limit of 33 officers in a divisional HQ, the Germans planned to have 30 - in stark contrast to a US divisional staff of 79. Again, this fitted with a force which would be attacking and making many more decisions outside of the headquarters, which could therefore be leaner. The Versailles Treaty placed no limitations on
NCO numbers, and by 1922 the
Reichswehr had over 50% of enlisted manpower at NCO ranks, leaving only 36,000 privates. The high quality of German soldiers, made possible by the much reduced numbers forced by the treaty, meant that the
Reichswehr could employ NCOs in junior-officer roles (as platoon leaders, for example). This had two effects: • When the Germans officially
re-armed in 1933-34 they could easily promote these NCOs to officer positions as the army expanded. • A tradition developed of much greater
leadership, responsibility, and capability below the officer level, which fitted with the delegated-authority doctrine necessary for
Bewegungskrieg (war of movement), which calls for independent judgement and fast local decision-making. The increased demands upon NCOs required the new army to treat them differently than the old Imperial had - in order to support them in their efforts. Hence all NCOs were now to have a barracks-room of their own and all soldiers were to be much better accommodated and trained than before. In the 1920s the
Reichswehr often distributed soldiers throughout the country in battalion- and regiment-sized groups, only forming larger units for occasional exercises. This was part of the
Truppenamt's plan to train squads, platoons and companies in the new regulations and doctrines and when ready then combining them in battalion and regimental exercises. The battalion and regimental exercises started in 1924, and the first divisional exercises in 1926. During this time the
Truppenamt had the task of ensuring that old "trench warfare" and "positional warfare" tactics did not creep back into use. Cross-training régimes were reviewed, long-length operational order-writing was eliminated, and attack styles that took too long to prepare were eliminated. Innovation and flexibility for mobile warfare were stressed over the carefully planned methods used in static warfare. ==Chiefs of Troop Office (1919–1935)==
