Log Planners monitor the ___ and applicable systems for changes that may occur or be posted in applicable Newsgroups or email org boxes.

• A. ISR Feeds
• B. TPFDD
• C. Operational Orders
• D. Mission Data Network

Answer: (B)

The key idea is that log planners watch the Time-Phased Force Deployment Data to stay current with how and when units, equipment, and tasks are scheduled to move. The TPFDD is the authoritative deployment timeline, and any changes—such as updated movement timings, unit composition, or tasking—are reflected there and communicated through relevant Newsgroups or distribution email boxes. By monitoring the TPFDD and the related systems, planners can quickly see what’s changed and adjust transportation, support, and execution plans accordingly. Other options don’t fit because ISR feeds focus on intelligence data, Operational Orders are directives rather than deployment timing data, and the Mission Data Network is a communication platform rather than the source of deployment change notices.
