Since 1974, the Conflict Simulation Laboratory (CSL) has provided state-of-the-art simulation and modeling tools, including the Joint Conflict and Tactical Simulation (JCATS) and the JCATS Low Overhead Driver (JLOD).
JCATS is a discrete event, constructive simulation that simulates effects-based, entity-level conflict scenarios. JCATS may be used stand alone or in federations using High Level Architecture (HLA) or Distributed Interactive Simulation (DIS) bridges.
How to get JCATS
JLOD is a multi-sided, white cell simulation tool that models force interactions on a global-level down to the individual entity. Together, JCATS and JLOD enable world-wide conflict simulation with high-fidelity simulation in targeted areas.
How to get JLODALERT NOTICE:
JCATS and JLOD are transitioning to operate on RHEL v9. Versions 20.0 and 12.0 respectively are the last versions to operate on RHEL v8. They will also operate on RHEL v9. Upcoming versions 21.0 and 13.0 will operate solely on RHEL v9.
