In movement planning, what is the primary purpose of the TPFDD tie-in?

• A. To calculate crew rest cycles.
• B. To determine lift requirements and timing.
• C. To document casualty evacuation routes.
• D. To select clothing for personnel.

Answer: (B)

The main idea is that the tie-in connects the Time-Phased Force Deployment Data to transport planning so you can turn the deployment schedule into concrete lift needs. By linking the phased personnel, equipment, and sustainment data with available airlift and sealift assets, you can determine exactly how many transports are required and when they must be used. This keeps movement feasible and synchronized with asset availability, preventing gaps or bottlenecks in the rollout. Other elements like crew rest cycles, casualty evacuation routes, or clothing selection are handled in separate planning processes and don’t address matching capacity and timing to the deployment schedule.
