Application of the Quantified Judgment Method of Analysis of Historical Combat to Current Force Assessments

  • T. N. Dupuy


The major feature of Quantified Judgment Method of Analyses (QJMA) is the Quantified Judgment Model (QJM), which is a metheniatical simulation of historical combat. The QJM systematically converts recorded statistical and descriptive data on ground combat engagements into quantified assessments of the force strength and combat potential of the opposing sides, thus permitting a ratio of their relative combat power. It does so by modifying the recorded strength of each in men and weapons by values representing the variables of combat, to the extent the record permits. These modifiers include such tangible variables as posture, weather, terrain, air superiority, mobility, logistical effectiveness, and vulnerability, and such intangibles (which can sometimes be assessed from the records) as leadership, morale, training, and experience. To permit comparison of the combat power ratio of the QJM with the outcomes of the historical engagements which produced the data, outcomes are represented quantitatively in terms of mission accomplishment, relative spatial effectiveness (ground gaining or holding), and relative casualty effectiveness.
