concepts." A component of the airpower doctrine instruction takes place through classroom "wargames" that simulate theater-level combat operations. Prior to its disestablishment, the course has added a "combatives" element that applied the classroom instruction to the expeditionary combat culture of the modern Air Force. The disestablishment of ASBC was not due to any perceived shortcomings with the curriculum. Rather, given severe financial pressures on the service, it was determined that elimination of ASBC would save over $12 million annually ($13.4 million in 2018 dollars) in temporary duty travel and per diem costs for sending newly commissioned second lieutenants to Maxwell AFB while en route to their follow-on duty stations.
