Which communication tool is primarily used to support missions outside the wire?

The correct choice, Blue Force Tracker, is integral for missions conducted outside the wire due to its capability to provide real-time situational awareness and track the location of friendly forces. This tool enhances operational effectiveness by allowing units to monitor troop positions on a dynamic map, facilitating coordinated movements and reducing the risk of friendly fire. It operates through GPS technology and often connects to other command and control systems, ensuring seamless communication and data sharing among units engaged in various missions.

While field radios and satellite phones are also vital communication tools, they are generally more focused on voice communication rather than the tactical situational awareness offered by the Blue Force Tracker. Walkie-talkies, although useful for close-range communication, lack the sophistication and range required for operations outside the wire, making them less suitable for such missions. Thus, the advanced tracking and communication capabilities of the Blue Force Tracker make it the optimal choice for supporting missions beyond secure perimeters.
