Which type of information should be included in the Sustainment Sync Matrix?

Including key events by echelon and by phases of operation in the Sustainment Sync Matrix is vital for coordinating and managing logistics and support throughout various stages of a mission. This type of information allows for effective planning and synchronization of logistics with operational requirements. It establishes a clear timeline of significant activities, ensuring that all involved units or echelons are aligned and prepared for their respective roles at specific points in the operation.

The structure of the Sustainment Sync Matrix ultimately serves as a strategic tool that helps to identify critical milestones and points in time when support is needed, which can enhance communication and operational effectiveness among different teams.

While the other options—projected costs of resources, suggested personnel assignments, and training schedules of units—are certainly important elements of operational planning and resource management, they do not directly pertain to the specific synchronization of events critical to the sustainment phase of operations as effectively as the key events by echelon and phase.
