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 Brigadier General Leo Austin Kiley, United States Air Force, for exceptionally meritorious conduct in the performance of outstanding services to the Government of the United States as Deputy Chief of Staff, Weapons Effects and Tests Group, Field Command, Defense Atomic Support Agency, from 1959 to 1963. In this important position General Kiley managed the nuclear weapons effects tests programs in Nevada and Pacific areas. From 1963 to 1964 General Kiley managed all Department of Defense weapons effects tests at the Nevada and Pacific test sites, the last series of U.S. nuclear tests in the atmosphere before the current nuclear test ban treaty. He also played a major role in formulating plans for the nation’s present underground nuclear test program. The singularly distinctive accomplishments of General Kiley and his dedicated contributions in the service of his country reflect the highest credit upon himself and the United States Air Force.
