====''Aufmarsch I Ost''====
{{lang|de|Aufmarsch I Ost}} was for a war between the Franco-Russian Entente and Germany, with Austria-Hungary supporting Germany and the [[British Empire]] perhaps joining the Entente. The [[Kingdom of Italy]] was only expected to join Germany if Britain remained neutral; {{nowrap|60 per cent}} of the German army would deploy in the west and {{nowrap|40 per cent}} in the east. France and Russia would attack simultaneously, because they had the larger force and Germany would execute an "active defence", in at least the first operation/campaign of the war. German forces would mass against the Russian invasion force and defeat it in a counter-offensive, while conducting a conventional defence against the French. Rather than pursue the Russians over the border, {{nowrap|50 per cent}} of the German force in the east (about {{nowrap|20 per cent}} of the German army) would be transferred to the west, for a counter-offensive against the French. {{lang|de|Aufmarsch I Ost}} became a secondary deployment plan, as it was feared a French invasion force could be too well established to be driven from Germany or at least inflict greater losses on the Germans, if not defeated sooner. The counter-offensive against France was also seen as the more important operation, since the French were less able to replace losses than Russia and it would result in a greater number of prisoners being taken.{{sfn|Zuber|2010|pp=116–131}}
