The Full Form of JCM is‍ Joint Conflict Model.

The Joint Conflict and Tactical Simulation (JCATS) software program is a constructive battlefield simulation of conflict, at the individual soldier and vehicle levels. This software program has been available since the 1980’s and is used in modeling and simulation, and by the Services in determining possible outcomes for force-on-force exercises / training. The program is updated continually, and there is a Joint-Service board that oversees the upgrades and incorporates them into the software. For example, during 2010, the board requested that the Defense Threat Reduction Agency (DTRA), in partnership with the Lawrence Livermore National Laboratory (LLNL), develop a threedimensional (3D) visualization enhancement (including: custom configuration, 3D models and textures, and 3D view for the JCATS Analyst Workstation) for the software.
