At the beginning of the operation, the United States was testing many different versions of the situation awareness system. They finally decided on a system called ''Force XXI Battle Command, Brigade and Below System'' (FBCB2). The U.S forces in [[Iraq]] made the system interoperable with all its forces and [[British]] troops in [[Operation Enduring Freedom]]. Blue Force Tracking proved its ability to cut down fratricide in Iraq, and is used by US troops in [[Afghanistan]]. Recently the [[NATO]] forces in [[Afghanistan]] are combining the forces of the countries' tracking systems to achieve an interoperable, Friendly Force Tracking system. | At the beginning of the operation, the United States was testing many different versions of the situation awareness system.
