What is a Fragmentary Order (FRAGO)?

A Fragmentary Order, commonly referred to as FRAGO, is specifically designed to provide updates or modifications to existing orders rather than serving as a standalone directive. In military contexts, it allows commanders to promptly communicate changes, clarifications, or additional instructions based on evolving situations while ensuring that all personnel are aligned with the original intent of prior commands. This summary aspect is crucial for maintaining coherence and organizational readiness during operations.

The other choices do not fully capture the essence of what a FRAGO entails. While it might include elements related to support operations or other directives, its primary purpose is to refine or add to the information originally provided in prior orders, emphasizing its nature as an update rather than a new order altogether.
