Conflict Simulation Laboratory

Enabling high-resolution, data-driven conflict simulation for US military, domestic, and international partners

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.

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.

Thanks to the Commander of the 9CSB Polish Armed Forces and NATO Bydgoszcz for hosting an outstanding 11th JCATS International Users Forum in Gydnia, Poland, 23 – 25 May 2017.
