The record: Armies from antiquity until past the Napoleonic period fought in formation because individual soldiers are vulnerable. Battles were usually contests between blocks of men holding together, and the side whose formation broke first usually lost. Further, maintaining clear formations was essential to maintaining battlefield operations and communication, both for commanders to be able to give orders to their subordinate officers as well as for individual soldiers to know where to rally and position themselves.
