The usual solution to this difficulty [maneuvring units on the battlefield] often goes by the terms “drill” or “discipline” though we should be clear here exactly what we mean. Discipline in particular has a number of meanings: it can mean the personal restraint of an individual, a system of rewards and punishments (and the effects of that system; the punishments are typically corporal) and what we are actually interested in: the ability of a large body of humans to move and act effectively in concert (all of these meanings are present to some degree in the root Latin word disciplina). For clarity’s sake then I am going to borrow a term (as is my habit) from W. Lee, Waging War (2016), synchronized discipline to describe the “humans moving an acting in concert” component of discipline that we’re most interested in here. That said, it is worth noting that those three components: personal restraint, corporal punishments and the synchronized component of discipline are frequently (but not universally) associated for reasons we’ll get to, not merely in the Roman concept of disciplina, but note also for instance their close association in Sun Tzu’s Art of War in the first chapter (section 13).
The reason we cannot just call this “drill” is because while drill is the most common way agrarian societies produce this result, it is not the only way to this end. For instance as we’ve discussed before, steppe nomads could achieve a very high degree of coordination and synchronization without the same formal systems of drill because the training that produced that coordination was embedded in their culture (particularly in hunting methods) and so young steppe nomad males were acculturated into the synchronicity that way. That said for the rest of this we’re going to place those systems aside and mostly focus on synchronized discipline as a result of drill because for most armies that developed a great deal of synchronized discipline, that’s how they did it.
Fundamentally the principle behind using drill to build synchronized discipline is that the way to get a whole lot of humans to act effectively in concert together is to force them to practice doing exactly the things they’ll be asked to do on the battlefield a lot until the motions are practically second nature. Indeed, the ideal in developing this kind of drill was often to ingrain the actions the soldiers were to perform so deeply that in the midst of the terror of battle when they couldn’t even really think straight those soldiers would fall back on simply mechanically performing the actions they were trained to perform. That in turn creates an important element of predictability: an individual soldier does not need to be checking their action or position against the others around them as much because they’ve done this very maneuver with these very fellows and so already know where everyone is going to be.
The context that drill tends to emerge in (this is an idea invented more than once) tends to give it a highly regimented, fairly brutal character. For instance in early modern Europe, the structure of drill for gunpowder armies was conditioned by elite snobbery: European officer-aristocrats (in many cases the direct continuation of the medieval aristocracy) had an extremely poor view of their common soldiers (drawn from the peasantry). Assuming they lacked any natural valor, harsh drill was settled upon as a solution to make the actions of battle merely mechanical, to reduce the man to a machine. Roman commanders seemed to have thought somewhat better of their soldiers’ bravery, but assumed that harsh discipline was necessary to control, restrain and direct the native fiery virtus (“strength/bravery/valor”) of the common soldier who, unlike the aristocrat, could not be expected to control himself (again, in the snobbish view of the aristocrats).
In short, drill tends to appear in highly stratified agrarian societies, the very nature of which tends to mean that drill is instituted by a class of aristocrats who have at best a dim view of their common soldiers. Consequently, while the core of drill is to simply practice the actions of battle over and over again until they become natural, drill tends to also be encrusted with lots of corporal punishments and intense regulation as a product of those elite attitudes. And though it falls outside of our topic today it seems worth noting that our systems of drill to produce synchronized discipline have the same roots (deriving from early modern musket drill).
