Which document contains the JU# used for TADIL-J reporting?

• A. OPTASK T
• B. HARMONY
• C. OPTASKLINK II
• D. OPTASKLINK

Answer: (D)

The main idea here is that the JU#, the unit identifier used in TADIL-J reporting, is defined in the OPTASKLINK document. OPTASKLINK lays out how Link 11/TADIL-J messaging is structured, including the reporting formats and the unit identifiers that must be used across participating units. That’s why this document is the authoritative source for where the JU# comes from.

In practice, when preparing TADIL-J reports, you reference OPTASKLINK to ensure you’re applying the correct JU# and formatting, so all nodes on the network recognize and route information consistently. The other documents listed are related to different aspects or revisions of data-link operations, but they do not specify the JU# for TADIL-J in the way OPTASKLINK does.
