What role may CRC assume for TDL management?

• A. JICO or MICO.
• B. RICO or SICO.
• C. ATO or CAO.
• D. HICO or BICO.

Answer: (B)

Managing tactical data links hinges on clearly defined interface control roles that oversee standards, configurations, and routing across all participating units. The CRC, as a central relay and coordinator for TDL traffic, fits best in either a Regional Interface Control Officer role or a Sector Interface Control Officer role. In a Regional ICO capacity, the CRC would supervise the data link interfaces for all forces within a geographic area, ensuring consistent data formats, timing, and routing rules so messages flow smoothly across the region. In a Sector ICO role, the CRC would manage interfaces for a specific air defense sector, coordinating interoperability within that sector and with adjacent sectors or higher echelons to maintain a coherent, shared picture.

Other ICO types exist for specialized contexts, such as joint or maritime environments, and are not the typical fit for a CRC in this land-based air defense C2 context. Roles focused on tasking or authority are not about data link interfaces, and other host- or battle-focused ICOs do not align with the CRC’s centralized relay and coordination function.
