What the Royal Navy expected war games to teach

The Admiralty's Tactical Division issued a common framework that could be used from individual-ship drills through fleet exercises. The manual separated cruiser problems, strategical exercises, mining and minesweeping, aviation, and communications. Strategical was the broader period term, although strategic later became standard. Its stated goals included teaching the battle plan, building common tactical doctrine, testing new ideas and material, and encouraging subordinate initiative. Officers also had to learn the capabilities of foreign ships and apply realistic navigation errors to aircraft operating as independent formations. War might begin anywhere and bring together ships from different stations at short notice, so shared methods were essential to making an improvised force work together. The rules linked tabletop decisions, staff training, and practical fleet exercises into one system of readiness.
