JCATS Low Overhead Driver (JLOD) is a joint multi-sided, real-time, high resolution, interactive computer-based simulation that models force interactions on a global level down to the individual soldier. Designed as a White Cell tool, JLOD provides wrap around signatures for JCATS and the Joint Live Virtual Constructive (JLVC) federation.

World-wide representation of distributed operations is provided using HLA as its backbone and generating position and other tactical signatures for stimulation of C4I systems. JLOD is JLVC-focused and is designed to portray large entity counts, movement for military and civilian operations, and TBM/IAD network play.

JLOD also has a stand-alone planner tool enabling operators to plan orders in parallel to an ongoing exercise ensuring order correctness and proper signature generation before they are injected into the exercise.
