Which stage of bare base development occurs within 72 hours after arrival?

The Initial Stage of bare base development is characterized by the rapid setup of essential systems and infrastructure that allow for basic operations to begin. This stage typically occurs within the first 72 hours after a unit has arrived at a site. During this time, priority is given to establishing the necessary resources for personnel, such as shelter, sanitation, and supply chains, to support immediate operational needs.

This prompt action is crucial, as it lays the foundation for subsequent stages of development, where capabilities are expanded and enhanced. The emphasis on setting up essential functions quickly is what defines the Initial Stage, making it the correct response to the question about when this phase occurs. The focus during this period is on achieving a minimum level of operational readiness to support any ongoing missions effectively.
