What type of order is a FRAGO?

A FRAGO, which stands for Fragmentary Order, serves as an abbreviated form of an operation order. It is used to provide changes or updates to existing plans, as opposed to issuing a completely new operation order. The primary purpose of a FRAGO is to streamline communications and make quick changes based on evolving situations, allowing units to adapt without the need for extensive re-briefing or documentation.

In the context of military operations, the efficiency of disseminating information is crucial, and a FRAGO addresses this need effectively by condensing key details into a shorter format.

Other options describe different types of documents or orders that do not capture the specific purpose and function of a FRAGO, further reinforcing why identifying it as an abbreviated form of an operation order is accurate in the context of military decision-making processes.
