Which unit is responsible for guiding the aircraft and de-rigging the load?

The receiving unit is responsible for guiding the aircraft and de-rigging the load during air assault operations. This responsibility is crucial as the receiving unit ensures that the load is safely and accurately positioned for unloading. They coordinate with the aircrew to provide timely guidance, taking into account factors such as wind conditions and the type of load being delivered. This function helps maintain operational efficiency and safety during the airdrop or sling-load operation.

On the other hand, the maintaining unit typically focuses on equipment upkeep and readiness, while the transport unit primarily handles the logistics of moving troops and supplies. The logistics unit may oversee broader supply chain activities, but it does not directly engage in the guidance or de-rigging tasks. Thus, the receiving unit plays a central role in the specific tasks outlined in the question.
