What priority designator indicates an emergency requisition?

The priority designator that indicates an emergency requisition is Priority 01. This designation is used for situations where immediate action is necessary to meet a critical need. It typically applies to items that are vital for the maintenance of military readiness, safety, and mission accomplishment in urgent circumstances.

Emergency requisitions can occur in various scenarios, such as equipment failures during operations or urgent replenishment of essential supplies. Priority 01 ensures that these urgent requests are processed ahead of other requisitions, minimizing delays in obtaining the necessary resources.

Other priority designators, while important, serve different purposes. For instance, Priority 03 might be used for routine supply needs, which are not as time-sensitive as an emergency requisition. Priority 05 designates less urgent demands, and Priority 09 relates to non-critical requests. Thus, Priority 01 clearly stands out as the correct choice for emergency situations.
