This thesis provides a foundation to build a new theater level computerized wargame for the Air Force Wargaming Center, Maxwell AFB, Alabama to replace the Theater War Exercise (TWX), also known as Agile. Given a recently developed land battle, this thesis' effort links United States Air Force doctrine with a conceptual model framework and designs a new air battle module. The integration of both the air and land battles forms a new game, SABER. This thesis redefines the ground combat units of the land battle, and adds theater air defense units, bases and aircraft packages. This thesis introduces stochastic attrition between the aircraft, ground forces, and theater air defense by joining together unclassified engineering submodels to gain credible interactions between the aggregated entities. The main components of SABER are stochastic attrition, formation of aircraft packages, logistics, intelligence, and nuclear warfare. The goals are to provide and document the algorithms and the related formulas for programmers to construct an object oriented computer simulation.
