Not only did Prussia take note of the problems in transporting supplies to armies, but it also took note of the lack of communication between troops, officers, and generals. Austria's army was primarily composed of Slavs, but it contained many other ethnicities as well. Austrian military instruction during peacetime utilized nine different languages, accustoming Austrian soldiers to taking orders only in their native language. Conversely, in an effort to augment the efficacy of the new “precision rifle” developed by the monarchy, officers were forced to only speak German when giving orders to their men. Even one Austrian officer commented at Solferino that his troops could not even comprehend the command, “Halt.” This demonstrates the "communicative" problems that arose quickly with the advent of the mass army.
