Which military branch was mentioned second?, Context: During the 1920s and 1930s, British civil servants and politicians, looking back at the performance of the state during World War I, concluded that there was a need for greater co-ordination between the three Services that made up the armed forces of the United Kingdom—the British Army, the Royal Navy, and the Royal Air Force. The formation of a united ministry of defence was rejected by David Lloyd George's coalition government in 1921; but the Chiefs of Staff Committee was formed in 1923, for the purposes of inter-Service co-ordination. As rearmament became a concern during the 1930s, Stanley Baldwin created the position of Minister for Coordination of Defence. Lord Chatfield held the post until the fall of Neville Chamberlain's government in 1940; his success was limited by his lack of control over the existing Service departments and his limited political influence.
