During this time he published two articles in the United States Naval Institute magazine Proceedings. The first, on the "Probability and Accuracy of Gun Fire", was a technical article arguing for more rather than bigger guns on battleships and cruisers. The Washington Naval Conference would prevent these ideas from being put into practice, by restricting the number and size of warships and their guns. The second, entitled "Naval Corps, Specialization and Efficiency", argued for increasing the specializations of line officers rather than creating separate corps of specialists, a more controversial topic at a time when naval aviators were agitating for the creation of a new specialist branch of their own. In 1922, Kinkaid became Assistant Chief of Staff to the Commander U.S. Naval Detachment in Turkish Waters, Rear Admiral Mark L. Bristol. This tour saw the end of the Greek occupation of Smyrna. The ratification of the Treaty of Lausanne by Turkey resulted in a draw-down of U.S. naval forces in the region, reducing Bristol's post to a primarily diplomatic one. In 1924, Kinkaid, whose father had died in August 1920, requested a posting back to the United States owing to his mother's ill-health. The ship taking him back, the light cruiser , had to sail by way of Iran in order to collect the body of Vice Consul Robert Whitney Imbrie, who had been killed by an angry mob in Tehran. Kinkaid received his first command, the destroyer , on 11 November 1924. Since its home port was the Philadelphia Navy Yard and ships' captains did not have to spend their nights on board, Kinkaid was able to live with Helen at her parents' residence in Philadelphia. In July 1925, he was assigned to the Naval Gun Factory. He was promoted to commander in June 1926. For the next two years, he served as Fleet Gunnery Officer and Aide to the Commander in Chief, U.S. Fleet, Admiral Henry A. Wiley. In 1929 and 1930, Kinkaid attended the Naval War College. This was followed by duty on the Navy General Board. He was then seconded to the State Department as a Naval Advisor at the Geneva Disarmament Conference. Kinkaid next became executive officer of , one of the navy's newest battleships, in February 1933. By coincidence the ship was at anchor in Long Beach, California, when the 1933 Long Beach earthquake struck. Over the next few days thousands of sailors
