What is the 'Latest Arrival Date' (LAD)?

The 'Latest Arrival Date' (LAD) is defined as the latest date a unit or personnel can arrive at their designated location to successfully meet operational requirements. This concept is critical in military planning, ensuring that all units and personnel are in place in time for missions or operations. Understanding the LAD helps planners coordinate logistics, troop movements, and other necessary actions to fulfill operational timelines.

In contrast, the other options describe related logistical concerns but do not define LAD. For example, while the deployment dates and resupply shipments are vital components of operational preparedness, they do not align directly with the core understanding of LAD, which focuses specifically on personnel and unit arrival timelines. Thus, the emphasis on timely arrivals is paramount in ensuring mission success, making option C the correct choice.
