Ragnar Colvin teaches command decisions through integrated staff work

Ragnar Colvin was an experienced all-round naval officer who later became Chief of the Australian Naval Staff as war approached. In Australia he had to help a political leadership understand what naval investment, force development, and sustainment would be required for the coming conflict. At Greenwich he emphasized scenarios and the reasoning behind command decisions: how an officer would interpret a situation, choose an approach, and coordinate the staff response. He also pressed different staffs and courses to work together rather than treating each specialty as an isolated school. War College work supported Admiralty planning during rearmament, including studies used by Third Sea Lord Reginald Henderson. Under Colvin, Greenwich came close to functioning as a naval university, combining professional teaching with cross-institutional cooperation and think-tank work.
