This monograph provides an in‐depth historical study of the evolution of Air Force–Army cooperation through the development and implementation of 31 specific initiatives designed to integrate and optimize joint air–land combat operations. It traces the evolution of air–ground relationships from the early 20th century through World War II, the Korean and Vietnam Wars, to the post-Vietnam era marked by the emergence of the AirLand Battle doctrine and the TAC–TRADOC dialogue. The work details the formation of joint groups such as the Joint Force Development Group and the Joint Assessment and Initiatives Office (JAIO), which were tasked with overcoming traditional service parochialism by formulating initiatives that address a wide range of issues—from air defense (including area and point missile systems, heliborne assault countermeasures, and IFF improvements) and rear area operations to joint munitions development (such as the Joint Tactical Missile System) and integrated command and control systems linking close air support, battlefield air interdiction, and intratheater airlift. The study highlights how these initiatives, supported by high-level agreements and cross-service participation in Program Objectives Memoranda (POM), sought to eliminate duplication, reduce costs, and build a cohesive, interoperable force capable of executing effective joint warfare. Overall, the monograph not only documents concrete doctrinal and organizational changes but also serves as a case study in innovation imposed from the top down, emphasizing key concepts like J-SEAD, AirLand Battle, and joint force development as critical to future military success.
