Apportionment and Tactical Airpower in AirLand Battle -- An Evaluation of CAS, BAI and AI from an Operational Perspective

This monograph examines the relative effectiveness of three key Air Force ground support missions: Close Air Support (CAS), Battlefield Air Interdiction (BAI), and Air Interdiction (AI). The costs and benefits associated with each mission are examined in light of the missions ability to influence the outcome of major operations and campaigns rather than local tactical engagements. The various missions are examined with respect to their ability to disrupt enemy operations by delaying, diverting, and destroying forces. They are also evaluated in light of the degree to which they complement or supplement ground force power. The study concludes that while there are no fixed rules to govern apportionment decisions, there appear to be some basic principles which one can apply to the apportionment process regarding the relative utility of the three stated missions.
