The Four Generations

[bemildred]

The First Generation of modern war began with the Peace of Westphalia in 1648, which ended the Thirty Years War. It also marked the state's assumption of a monopoly on war; thereafter, war became something waged by states, for raison d'etat, with state armies and navies doing the fighting. The First Generation ran from 1648 to about the time of the American Civil War, and it was characterized, on the whole, by a battlefield of order. The battlefield of order created a military culture of order, which endures to this day.



And there's the rub. For around the middle of the 19th century, the battlefield of order began to break down. Ever since, state militaries have had to grapple with a growing contradiction between their internal culture of order and the external reality of an increasingly disordered battlefield.



The Second and Third Generations represent two different approaches to that problem. Second Generation war was developed by the French Army during and after World War I, and is best summed up with the French saying, "The artillery conquers, the infantry occupies." Also known as firepower/attrition warfare, Second Generation war maintained the First Generation culture of order. Decision-making was centralized and hierarchical; orders were detailed and controlling, to permit synchronization of all arms; time was not particularly important; and success was measured by comparative body counts. Second Generation armed forces focus inward on methods, processes and procedures, prize obedience over initiative (initiative and synchronization are not compatible) and depend on imposed discipline. The American Army and Marine Corps learned Second Generation war from the French during the First World War and still practice it today, with exceptions based on individual commanders.



Third Generation war, also known as maneuver warfare, was developed by the German Army in World War I; by 1918, Blitzkrieg was conceptually complete, lacking only the tanks necessary for operational mobility. The Prussian/German roots of Third Generation war go back earlier, to the Scharnhorst reforms that followed Prussia's defeat by Napoleon. One of those reforms changed what was required of a Prussian officer; instead of being responsible for obeying orders, he became responsible for getting the result the situation required regardless of orders (in 19th century war games, it was common for junior Prussian officers to be given problems that could only be solved by disobeying orders). This in turn created a military culture that was focused outward, on the enemy, the situation and the result the situation demanded instead of inward on rules, orders and processes. In effect, Prussia had broken with the First Generation culture of order.

2. The Canon, Continued

This column, the third in a series, concludes a discussion of the canon, the seven books which, read in the order given, will take the reader from the First Generation of modern war through the Fourth. As one Marine Corps captain, an instructor at The Basic School, said, "Unless the guy's a rock, he can't read these books in the right order and not get it."
