Which of the following is NOT a main aspect of logistics support planning?

Logistics support planning encompasses various critical components aimed at ensuring that operations run smoothly and efficiently. One essential aspect of it includes positioning forces effectively to optimize their operational capabilities, which ensures that the right resources are available at the right time and place. Documenting the return process is vital to manage the logistics of returning equipment or resources after missions, and sustaining operations during missions is crucial for maintaining effectiveness throughout the duration of these operations.

While establishing assessment capabilities may be important in broader logistics management and general operational strategies, it is not a core element of logistics support planning itself. Logistics support primarily focuses on the practical elements that enable mission success, like resource allocation and operational continuity, rather than evaluating or assessing those logistics processes. Thus, the correct option reflects an aspect that, while related, does not directly fit within the fundamental framework of logistics support planning.
