In 1961, as Chairman of the Tactical Mobility Requirements Board, Howze led the development in airmobile theory and doctrine. The army's adoption of the recommendations in the Howze Board changed mobile warfare. Its revolutionary concepts – based on the use of aviation – changed military attitudes in a similar manner to the way the tank affected ideas on mobility 50 years earlier. Two years later the 11th Air Assault Division was formed to test and validate these concepts. As a result of Howze's leadership, foresight and perception, two air-mobile divisions were eventually established. These divisions, which still adhere to the fundamentals of Howze's air-mobility doctrine, have gone on to provide mobile and combined arms capabilities that are required in today's ground combat conditions.
