Who should services personnel work with to determine boots on ground and inbound personnel?

The appropriate choice for determining boots on ground and inbound personnel is Personnel Support for Contingency Operations (PERSCO). This unit is specifically tasked with managing personnel accountability and support during deployments and operations. PERSCO provides essential oversight for tracking personnel movement, ensuring that all personnel are accounted for during missions and that they are appropriately supported in terms of logistics and resources.

In contrast, while Logistics Command focuses on the transportation and supply chain aspects, it does not directly handle personnel tracking and accountability. Mission Command is concerned with the overall command and control of military operations rather than specific personnel management. An Intelligence Unit provides critical information regarding roles, threats, and operational environment but does not manage personnel deployment logistics.

Therefore, PERSCO is the most specialized unit equipped to address the unique challenges of tracking and managing personnel in the context of deployment and operations, making it the correct choice.
