What symbol appears next to the track number when the classification processor in the CTCP card identifies tracks on the Sentinel?

When the classification processor in the Command and Tactical Control Processor (CTCP) card identifies tracks on the Sentinel, a specific symbol is used to indicate this identification process. The plus symbol signifies that the track has been classified and is now recognized as a legitimate track. This classification is essential for distinguishing friendly tracks from hostile ones and effectively managing air defense operations.

The other symbols represent different statuses or categorizations of tracks but do not convey the same clear indication of successful classification that the plus symbol does. Properly understanding these symbols is crucial for air defense personnel, as they directly relate to situational awareness and the operational response to identified threats in the airspace.
