What code would indicate a critical supply need that impairs mission?

The code that indicates a critical supply need that impairs mission is recognized as UND B. This designation signifies that the supply is essential and its absence would significantly hinder the ability to carry out operational missions. In supply requisition management, understanding the implications of different codes is crucial because it helps prioritize requests and ensures that resources are allocated effectively.

In this case, UND B is particularly important as it conveys a sense of urgency for the requested items. When a supply request is marked with this code, it alerts supply personnel to prioritize the order to support mission readiness. Ensuring that these critical items are available directly affects operational capabilities, thus emphasizing the importance of accurate coding in requisition processes.
