In contingency planning, what identifies the specific forces and resources required to execute the plan?

The correct choice is OPLAN, which stands for Operations Plan. An OPLAN is a complete and detailed plan that describes how a specific military operation will be implemented, including the objectives, forces involved, logistical considerations, and the resources necessary to accomplish the mission. In contingency planning, the OPLAN is crucial as it outlines the comprehensive strategy for deploying the specific forces and resources needed for the successful execution of the military operation.

In this context, while CONPLAN refers to a concept plan that outlines the broad concept for an operation without detailing the forces and resources required, TPFDD, or Time-Phased Force and Deployment Data, pertains to the actual timelines and movements of forces and equipment but does not encapsulate the entire operational framework or vision. FRAGO, or Fragmentary Order, provides additional information or changes to an existing operation but does not establish the initial framework for forces and resources needed for a new operation. Therefore, OPLAN stands out as the most comprehensive and specific identification of required forces and resources in contingency planning.
