The Counter Insurgency (COIN) Experiment was performed in March 2007 using a distributed network. It was focused on simulating urban operations in Central Asia in 2015. A major goal of the experiment was to demonstrate the use of a complex Models and Simulation federation to train and evaluate doctrine for a Counter Insurgency Environment. Participating federates included OFOTB, FireSim, JSAF, CultureSim, EADSim, CMS2, Universal Controller, ACRT, ACRT-DR, JNEM, ISM, SAServer, MC2, CERDEC CES, AOIServer, EffectsServer, Reporter, DataLogger, SEAMS. This was an entity-level distributed simulation event that included sites at Ft Knox, Ft Sill, Ft Bliss, and Huntsville, using the DIS and HLA protocols. Approximate entity counts included 1000 US vehicles and soldiers, 1000 Local Police and Army, 1200 insurgents, and 20,000 civilians from various population groups.

Several new and enhanced models contributed to the richness of the COIN environment. A Force model was developed that allowed each station to control its rules of engagement, crucial for a situation where the enemy depended on who and where you were. A model of uniformed entities versus plain clothes was added since insurgents don't generally show themselves as such. JNEM/ISM provided real-time feedback on the mood of the various civilian population groups. A new model of IEDs was developed that simulated several trigger types, decoys and countermeasures. Suppressive effects were added including non-lethal rounds. The area-of-interest model was improved to allow good simulation performance in a dense urban environment. The terrain database had 10000 fully modeled multi-elevation buildings along with 650,000 volume buildings.
