FBCB2 / Blue Force Tracker (1990s-2000s)
The Army fielded Force XXI Battle Command Brigade and Below, its first digital command and control system, in the early 2000s. Built by a single vendor, it displayed friendly and enemy positions on digital maps for brigade and below units.
FBCB2 improved situational awareness in Iraq and Afghanistan but was difficult to update and integrate with other systems.
Its limitations helped drive the Army's shift toward modular, open architectures for command and control.
FBCB2 shows the problems with single-vendor, monolithic C2 systems that NGC2 is designed to avoid.
