Summary: Friendly fire incidents, or fratricide, accounted for about 24 percent of U.S. fatalities during Operation Desert Storm in 1991. Since then, the Department of Defense (DOD) and the military services have been working to find new ways to avoid friendly fire in joint and coalition operations. Preventing friendly fire is a complex and challenging endeavor. It encompasses the development of new technologies as well as new training, tactics, and warfighting techniques. It involves a range of equipment and systems that have historically not been able to effectively interact as well as various military operations. It is a concern among each of the services as well as U.S. allies. Clearly, it is essential to have a blueprint that ties together these elements and provides a comprehensive map for long-term improvements as well as a management framework that is strong enough to implement the blueprint. Although DOD has taken some concrete steps toward both ends, it needs to strengthen these efforts and ensure that they are supported by the services. Otherwise, it may continue to contend with problems leading to friendly fire incidents.
