What is FRAGO?

FRAGO meaning in Military terminology / glossary / dictionary is:
A change in the OPORD that does not require a wholesale change in the OPORD. A FRAGO determines timely changes to an already existing order. The important point here is that a frag order is issued based on the basic operation order and is not a “stand alone” directive. It will normally state the changes from the basic order such as enemy situation and new taskings.
