The President of the United States of America, authorized by Act of Congress, 20 July 1942, takes pleasure in presenting a Bronze Oak Leaf Cluster in lieu of a Second Award of the Legion of Merit to Colonel William Wallace Momyer (ASN: 0-22862/FR-1964), United States Air Force, for exceptionally meritorious conduct in the performance of outstanding services to the Government of the United States during the period 12 June 1951 to 7 July 1953. As Director and later as Deputy Commandant for Evaluation, Colonel Momyer directed the work of the Evaluation Staff of the Air War College. In these capacities he was charged by the Air Force with responsibility for developing strategy, concepts and doctrine for the command and employment of air power. During this period the demands on the Evaluation Staff increased sharply in number and scope largely because of the uncertain course of international events. Furthermore, many of the projects were urgent in their relation to specific actions to be taken by the Air Force in performing its assigned mission. Colonel Momyer met all the requirements placed within his responsibility with outstanding skill and thoroughness. As a direct consequence, the progress of the Air Force during this critical period was aided materially in the fields of weapons systems, command arrangements, policy and doctrine, development programs, joint action by the armed forces, and tactics, strategy and techniques. The success with which he discharged his duties and the effectiveness and energy with which he employed his individual capabilities were instrumental in furthering the objectives of the Air Force in support of its responsibilities for national security.
