This paper presents two important interoperability issues for computer-generated forces. The first is fundamental and concerns the inconsistent representation of interfiring times of direct-fire weapons in ground combat in entity-level (i.e. discrete-event) and aggregated-force (with attrition modeled by Lanchester-type equations) combat simulations. The second is behavioral and again concerns inconsistent representation of platform-level command and control in such combat in entity-level and aggregated-force simulations. This second inconsistency concerns combatsystem behavior in acquiring and attacking (i.e. firing at) enemy systems, i.e. whether or not new targets can be acquired while an enemy target is being engaged. Computational evidence of the seriousness of the consequences of such inconsistencies on simulation output is presented. This paper shows how they can be avoided by appropriate mathematical modeling of Lanchester attrition-rate coefficients in aggregated-force combat simulations. Without such modeling, however, fundamental inconsistencies (with significant consequences) currently exist between all entity-level and aggregated-force combat simulations.
