The U.S. Army and Republic of Korea Army successfully conducted a large-scale, distributed command post training exercise with more than 250 participants using technology developed by Lockheed Martin.

The Full Spectrum Exercise (FSX) concluded this month, leveraging the Warfighters' Simulation (WARSIM) and the WARSIM Intelligence Model as the major components of the Joint Land Component Constructive Training Capability (JLCCTC) Multi-Resolution Federation-WARSIM training system.

The test was conducted for the U.S. Army Program Executive Office of Simulation, Training and Instrumentation.

Through WARSIM, battle commanders, staffs and units from the U.S. Army 2nd Infantry Division and South Korea were able to connect across numerous locations in Kansas, Virginia and Korea for the eight-day, 180-hour exercise.

As part of JLCCTC, the WARSIM program is designed to simulate all types of conflict - from major theater-level operations to stability and support missions - at the brigade, joint and coalition levels.

"Mission success largely depends on training together," said Jim Craig, vice president of training systems at Lockheed Martin's Global Training and Logistics business unit.

"WARSIM is a reliable, adaptable system that makes it possible for commanders and staff to conduct essential training exercises that simply couldn't take place live because of cost, distance and logistics."

In addition to the FSX, the U.S. Army and South Korea conducted another exercise with WARSIM, called Warpath II, in October. That exercise linked more than 200 participants across Hawaii, Virginia and three separate locations in South Korea.

The exercise lasted 164 hours and included both a low-intensity phase and a high-intensity, force-on-force phase, which enabled participants to experience realistic warfighting scenarios within a coalition environment.
