With the military becoming increasingly involved in Stability and Support Operations (SASO), preparing personnel for challenges pre-deployment is critical. In 2000, we attended peacekeeping training sessions for the 3rd Infantry Division (3ID) as it prepared for rotation into Bosnia, and we traveled to Bosnia to observe their rotation with the outgoing unit. We found that while their training prepared them to fight and protect their safety, it did not prepare them for the geopolitical environment, decisions they would make, an understanding of available resources, or how information flows between team members. Sponsored by the Army Research Laboratory, we developed a distributed training simulation to prepare future units to contend with these challenges in peacekeeping missions. The tool, an electronic decision exercise, provides an overview of the political and cultural climate in the region, maps of the region, and a simulation exercise based on actual events during the 3ID tour. Based on real-world experiences, the simulation provides a richer understanding of in-country conditions. A secondary focus of this tool was the development of adaptive teams: gaining shared situation awareness, problem solving, and selecting courses of action. Since soldiers are often deployed with people they've never met, this tool allows individuals to work online simultaneously to "get to know" their team members before deployment. As they work through the simulation exercise, they trade information and calibrate their expectations regarding information sharing, decision making, and resource allocation. Finally, this tool provides an opportunity for incoming units to learn from incumbents. The Command and General Staff College at Ft. Leavenworth evaluated the tool and found it to improve knowledge of resources, skills in applying resources, and the ability to act more quickly and efficiently when faced with real life problems. The tool is now part of the CGSC tactics course.
