The Joint Integrated Contingency Model (JICM) is a very large simulation system that encompasses the strategic and operational levels of land, air, and naval warfare with a global set of models and databases. An annotated briefing adapted from a class, this document is a user manual for the ground combat portion of the JICM. It is an overview of the terrain, forces, and combat processes; the orders that manage combat; the parameters that set combat rates; and the displays that show what is occurring. It assumes that the reader is familiar with the operation of the JICM system software and the orders necessary to move ground forces to the theater of combat.
