Abstract

We have used detailed, entity-level models to simulate the effects of long-range precision fires employed against an invader. Results show that these fires are much less effective against dispersed formations marching through mixed terrain than against dense formations in open terrain. We expected some loss of effectiveness, but not as much as observed. So we built a low resolution model (PEM, or PGM Effectiveness Model) and calibrated it to the results of the detailed simulation. PEM explains analytically how various situational and tactical factors, which are usually treated only in complex models, can influence the effectiveness of these fires. The variables we consider are characteristics of the C4ISR system (e.g., time of last update), missile and weapon characteristics (e.g., footprint), maneuver pattern of the advancing column (e.g., vehicle spacing), and aggregate terrain features (e.g., open versus mixed terrain).
