Which CRC function is used to determine friend or foe among contacts?

• A. Air Surveillance
• B. Airspace Management
• C. TDL Management
• D. Combat Identification

Answer: (D)

Combat Identification is the process used to determine whether a contact is friendly or hostile by validating its identity against known friend or foe data and criteria. It combines sensor information, identification cues (like IFF responses), track history, and shared data from networks to assign a friend or foe status, guiding engagement decisions and ROE. The other options describe support functions: Air Surveillance detects and tracks objects but doesn’t establish identity by itself; Airspace Management focuses on how airspace is used, not who a contact is; TDL Management handles the flow of data between systems, not the identity decision.
