We must revitalize wargaming to prepare for future wars, Deputy Secretary of Defense Bob Work and Gen. Paul Selva argue:
Few historical periods match the dynamic technological disruption of the inter-war years of the 1920s and 1930s. During these decades, militaries the world over struggled to adapt to new inventions such as radar and sonar, as well as rapid improvements in wireless communications, mechanization, aviation, aircraft carriers, submarines, and a host of other militarily relevant technologies. Military planners and theorists intuitively understood that all these new technologies, systems, and advances would drive new ways of fighting, but they were forced to envision what future battlefields would look like with few clues to go by.
To help navigate through this period of disruptive change, the United States military made extensive use of analytical wargaming. Wargames were an inexpensive tool during a period of suppressed defense spending to help planners cope with the high degree of contemporary technological and operational uncertainty. They were used to explore a range of possible warfighting futures, generate innovative ideas, and consider how to integrate new technologies into doctrine, operations, and force structure. For example, faculty and students at the Naval War College integrated wargaming into their entire course of study, analyzing the then-novel concept of carrier task force operations, the role of submarines in scouting and raiding, and how to provide logistics support to fleet operations spread over the vast Pacific Ocean. Wargames in classrooms at Quantico helped the Marine Corps develop new concepts for amphibious warfare and conceive of new techniques for capturing advanced naval bases. Wargamers at the Army War College explored how to employ tanks and artillery on infantry-dominated battlefields and examined the logistical challenges of fighting a war far from American shores.
As valuable as they were, wargames were not in and of themselves sufficient to prompt organizational and operational change. As such, all of the services worked hard to test wargame results in fleet and field exercises. Exercises were used to verify game insights using systems at hand or with surrogates that represented desired advanced capabilities identified during game play. The observations and lessons learned in exercises were in turn fed back into new wargames, thus creating a cycle of creative ideas and innovation that generated requirements for new systems, suggested new operation concepts, and influenced force design.
Once the Second World War began, those warfighting communities that had pursued wargaming and exercises with vigor proved far better prepared for modern combat than those that did not. For example, of the three major warfighting communities in the Navy — naval aviation, surface warfare, and submarine — the naval aviation community carried out the most innovative pre-war experimentation and exercises. Although aircraft carriers were originally envisioned as operating in support of the fleet battle line, carrier aviators explored a wide range of futures, including independent carrier operations. As a result, the U.S. carrier force was ready on day one of the Pacific war, and within six months had inflicted a major, lasting defeat on the superior Japanese carrier force at the Battle of Midway. By contrast, pre-war wargames and exercises in the submarine community had emphasized rote doctrine using the submarine fleet as a scouting force for the main battle line, and policy strictures dampened any exploration of independent submarine operations. Unsurprisingly, then, the submarine community proved unprepared for the tactics, techniques, and procedures needed to execute unrestricted warfare on Japanese merchant shipping. Similarly, surface warfare wargames failed to anticipate long-range torpedoes or account for the Japanese emphasis on night surface action. As a consequence, they suffered badly in early clashes against a highly trained Japanese cruiser and destroyer force that excelled at night fighting and was armed with the deadly, long-range Long Lance torpedo.
Today, we are living in a time of rapid technological change and constrained defense spending, not unlike that of the inter-war years.
The story of how the Navy learned to learn to fight is fascinating, by the way.
