What is the second piece of CIN?

• A. Defense group
• B. Functional CDR
• C. Sequence identifier
• D. Navy training region

Answer: (A)

CIN is a Course Identification Number used to uniquely label Navy training courses, built from multiple segments that encode region, category, sequence, and a final identifier. The second segment designates the Defense Group, which defines the broad category of the training the course belongs to. That’s why it’s the correct answer—the Defense Group is the portion of CIN that sits in the second position. The first segment identifies the Navy Training Region, the third segment is the Sequence Identifier, and the remaining piece handles the final designation or revision.
