Which activity is NOT part of ISR responsibilities?

• A. Maintain logs of target deck (eyes on/off, EEIs)
• B. Organize imagery for offboard dissemination
• C. Reformat images
• D. Send TACREP I reports for surface vessels

Answer: (D)

In ISR operations, the focus is on turning collected sensor data into usable intelligence and getting it to the right people. Keeping a running log of targets—with eyes-on and eyes-off statuses and the Essential Elements of Information—is part of that data management and target development process. It ensures you know what’s being watched, what’s known, and what still needs to be learned.

Organizing imagery for offboard dissemination is also squarely ISR work. It means preparing the imagery so other units or commands can access and use it, which is a key step in turning raw data into actionable information.

Reformatting images fits the same chain. Different recipients may require different formats or resolutions, so adjusting imagery to meet those needs is part of processing and distribution within ISR.

Sending TACREP I reports for surface vessels, however, is a reporting/coordination task that lies outside the core ISR processing workflow. It involves conveying established observations and details to ships via the appropriate tactical reporting channels, a function more about liaison and command communications than the ISR data processing and dissemination cycle.

So the activity not part of ISR responsibilities is the act of sending TACREP I reports to surface vessels.
