If contact with a unit is lost for 3 days, which aerial delivery distribution should be executed?

In the context of military operations, particularly during Large-Scale Combat Operations, maintaining supply lines and ensuring that units have the necessary resources is critical. When contact with a unit is lost for three days, it indicates a potentially serious situation where that unit may be isolated or unable to communicate its needs effectively.

The appropriate aerial delivery distribution to execute is a follow-up distribution. This option is designed to provide the necessary support to a unit that may be in distress or may require resupply without attempting to consolidate demands that have not been communicated. Follow-up distribution typically occurs when units have been out of contact for a designated period, resetting focus on ensuring they receive adequate resupply to sustain operations.

The other options, while relevant in different scenarios, do not fit this situation as effectively. Demand supported would imply the unit is capable of communicating needs, emergency would be more appropriate for immediate life-threatening needs, and accompanying typically refers to a situation where supplies are delivered along with a unit actively engaged. Thus, follow-up is the most suitable choice when contact with a unit has been lost for a specific timeframe, ensuring that it receives needed support promptly.
