c. Communications, particularly voice and data distribution radios, are important elements of
the Army Tactical Command and Control System (ATCCS) because they provide the means to
interconnect the components of the C2S2 architecture.
5. Summary. In this lesson, you learned about the need for battlefield automation. You also learned
how the battlefield is automated using the Command, Control, Subordinate Systems (C2S2) architecture
as it supports the five battlefield functional areas (BFA) of maneuver, fire support, air defense,
intelligence and electronic warfare, and combat service support. You also learned that the Force Level
Control System (FLCS) provides the C2 means for the commander and staff and the means of
coordination among the BFA.
