Abstract

This article develops a Lanchester‐type model of large‐scale conventional ground combat between two opposing forces in a “sector”. It is shown that nonlinear Helmbold‐type equations of warfare with operational losses may be used to represent the loss‐rate curves that have been used in many aggregated‐force models. These nonlinear differential equations are used to model the attrition of combat capability (as quantified by a so‐called firepower index) in conjunction with a rate‐of‐advance equation that relates motion of the contact zone (or FEBA) between the opposing forces to the force ratio and tactical decisions of the combatants. This simplified auxiliary model is then used to develop some important insights into the dynamics of FEBA movement used in large‐scale aggregated‐force models. Different types of behavior for FEBA movement over time are shown to correspond to different ranges of values for the initial force ratio, for example, an attack will “stall out” for a range of initial force ratios above a specific threshold value, but it will “break out” for force ratios above a second specific threshold value. Such FEBA‐movement predictions are essentially based on being able to forecast changes over time in the force ratio.
