Why strategists need not serve in uniform

The opening compares strategists with different service records. Mahan, Gorshkov, and Sims served as naval officers, James Cable served in the Army, and Julian Corbett had no military service. That range matters because wars are fought between countries, with civilian governments making the final decisions about where forces go. Generals, admirals, and their staffs recommend deployments and prepare plans, while leaders such as Winston Churchill, Franklin D. Roosevelt, and Neville Chamberlain decide how a country commits its forces. Strategic study gives civilian and military leaders a shared language for reasoning about war, so prior service is one source of knowledge rather than the sole qualification for strategic thought.
