A FRAGO — Fragmentary Order — is a condensed military order that modifies or supplements a previously issued operation order (OPORD) without replacing it. It exists because combat operations change faster than the full order process can accommodate. What It Is Military operations are planned through a formal process that produces an OPORD — a complete, five-paragraph operation order covering situation, mission, execution, sustainment, and command and signal. OPORDs can run dozens of pages.

A SITREP (Situation Report) and a SPOTREP (Spot Report) are both military reporting formats, but they serve fundamentally different purposes and operate on different timelines. Confusing them produces either stale information delivered promptly or current information buried in unnecessary structure. What They Are SITREP — Situation Report A SITREP is a periodic, comprehensive summary of the current operational situation. It is scheduled, structured, and cumulative. A unit submits SITREPs at fixed intervals — every six hours, every twelve hours, every twenty-four hours — as specified in the operation order.
