Though the military is full of corruption and fraud, there still exists minimum planning.
For example, France's Plan XVII for war against Germany.
Though they're now moving even their capital after losing the last border battle and being pushed back continuously, anyway France had plans too. Until getting beaten by the Prussian strong army.
Same for us. Long before Brusilov's appointment as offensive commander-in-chief, we Russia also had plans against Germany.
Of course, we didn't schedule train tickets by the minute and densely mark troop movement routes on maps like Schlieffen, but we had not one but two.
First, Plan A.
If Germany attacks France first, block Dual Monarchy forces coming up from southwest with one army group while advancing maximally into East Prussia.
Next is Plan G.
If Germany and the Austro-Hungarian Empire unite to come east. Focus on defense sending forces to Warsaw within two weeks.
