Military Reporting Formats Explained: SITREP, SPOTREP, FRAGO, OPORD and SALUTE
Military units pass two kinds of message: orders going down the chain and reports coming up. Both use fixed formats. The point is speed and completeness under stress. A tired platoon leader on a bad radio link doesn’t have to think about what to say next, and the person receiving the message knows exactly where to look for the grid reference. The formats also turn up far outside the army: emergency services, humanitarian agencies and corporate crisis teams all borrow the SITREP.
This page covers the main formats in US and NATO-style practice at the level of published doctrine and training material: the five-paragraph OPORD, the WARNORD and FRAGO that sit around it, and the SALUTE, SPOTREP, SITREP and 9-line MEDEVAC reports that travel back up.
Orders going down: OPORD, WARNORD and FRAGO
The operation order (OPORD) is the full written or spoken order for an operation. Almost every NATO-style army builds it on the same five paragraphs, which US Marines learn as SMEAC:
| Paragraph | What it covers |
|---|---|
| 1. Situation | Enemy forces (composition, capabilities, likely courses of action) and friendly forces (higher unit’s mission, adjacent units, attachments and detachments) |
| 2. Mission | One clear statement of who, what, where, when and why |
| 3. Execution | Commander’s intent, concept of operations, scheme of maneuver, fire support, tasks to subordinate units, coordinating instructions |
| 4. Sustainment (Administration and Logistics) | Supply, medical support and casualty evacuation, handling of prisoners |
| 5. Command and Signal | Where the commander will be, succession of command, frequencies, call signs, passwords |
At division level an OPORD can run to dozens of pages with annexes for intelligence, fires and communications. At squad level it may be a ten-minute talk around a map drawn in the dirt. The structure stays the same either way; that’s the point of it. British forces use a slightly longer sequence (preliminaries, ground, situation, mission, execution, service support, command and signal, then questions), but the core is recognisably the same.
The warning order (WARNORD, or WARNO) comes first. It tells subordinates an operation is coming so they can start preparing before the full order arrives. It has no rigid format; many units simply use the five-paragraph headings and fill in what they know. At minimum it gives the nature of the mission, who is taking part, the timing and when and where the OPORD will be issued. It also triggers the practical stuff: drawing ammunition, rations and water, checking radios. Good units send one as soon as they get a mission, and often send more than one as details firm up.
The fragmentary order (FRAGO) comes after. Once an OPORD is running, a FRAGO changes it without reissuing the whole thing. It follows the five-paragraph layout but fills in only what has changed, and everything else stands as ordered. A changed objective, a new route or a shifted start time is FRAGO material. FRAGOs can go out by radio in seconds and carry the same authority as the original order. The FRAGO entry has a worked example.
A typical sequence for a battalion operation: a WARNORD on receipt of the mission, a second WARNORD as the plan forms, the OPORD, then a string of numbered FRAGOs as the situation changes. The US Army’s troop leading procedures and the Marine Corps’ BAMCIS sequence (begin planning, arrange reconnaissance, make reconnaissance, complete planning, issue the order, supervise) are the planning routines that produce these orders at small-unit level.
Reports going up: SALUTE and the SPOTREP
SALUTE is the standard way to describe what you’ve seen of the enemy. Each letter is a field:
| Letter | Field | Example |
|---|---|---|
| S | Size | Six vehicles, about 20 dismounts |
| A | Activity | Moving north on the main road |
| L | Location | Grid reference |
| U | Unit (or Uniform) | Markings, insignia, uniform type |
| T | Time | When observed, not when reported |
| E | Equipment | Two fuel tankers, four cargo trucks |
Its job is to stop observers leaving out the field that matters. “Enemy trucks moving” is useless; “six trucks moving north at grid 123456 at 0730, two of them fuel tankers” is something a staff officer can act on. A shorter variant, SALT (size, activity, location, time), is used when there isn’t time or detail for the full set.
The spot report (SPOTREP) is the vehicle for that information. It goes out immediately, by whatever means is fastest, whenever something significant happens: contact with the enemy, a new position sighted, an IED found. It doesn’t wait for a reporting cycle. In most units the body of a SPOTREP is a SALUTE line.
Reports going up: the SITREP
The situation report (SITREP) is the opposite: scheduled, cumulative and broad. Units send SITREPs at fixed times set in the OPORD (every 12 or 24 hours is common), and a higher headquarters builds its picture of the area by stacking them. A typical SITREP covers the unit’s location and activity, enemy activity since the last report, own strength and casualties, logistics status (fuel, ammunition, water), and anything planned for the next period. A missing SITREP is itself information: it tells headquarters that something may be wrong.
The two are often confused, and the difference matters. A key sighting buried in the next scheduled SITREP might arrive hours late. SITREP vs. SPOTREP walks through how they fit together in one patrol’s day.
Outside the military, the SITREP is the format that has travelled furthest. Emergency management agencies, UN humanitarian coordination offices and corporate incident teams all issue situation reports, in the same spirit: a dated snapshot, sent on a schedule, with the same headings each time.
The 9-line MEDEVAC request
The 9-line is the request for a medical evacuation helicopter or ground ambulance. It is probably the most drilled format in the army, because the person sending it is often not a medic and is under fire. The lines are always sent in the same order:
| Line | Content |
|---|---|
| 1 | Location of the pickup site (grid reference) |
| 2 | Radio frequency and call sign at the pickup site |
| 3 | Number of patients by precedence |
| 4 | Special equipment needed (hoist, extraction gear, ventilator) |
| 5 | Number of patients, litter or ambulatory |
| 6 | Security at the pickup site (enemy presence, whether an escort is needed) |
| 7 | How the pickup site is marked (panels, smoke, signal light) |
| 8 | Patient nationality and status (own forces, allied, civilian, enemy prisoner) |
| 9 | CBRN contamination (in wartime) |
Line 3 uses precedence categories: urgent, urgent-surgical (urgent and needing surgery on arrival), priority and routine. Each category carries a target time for getting the patient to care, set in current medical doctrine; urgent is the shortest, and routine allows up to 24 hours. Peacetime and training versions change some lines, since enemy security and contamination usually aren’t the questions that matter.
The 9-line is for MEDEVAC proper: a dedicated, medically equipped vehicle with care en route. Casualty evacuation (CASEVAC) on whatever vehicle happens to be available is a separate thing.
The formats side by side
| Format | Direction | When | Structure | Purpose |
|---|---|---|---|---|
| WARNORD | Down | As soon as a mission is received | Loose; often the five headings, partly filled | Start preparation early |
| OPORD | Down | Before the operation | Five paragraphs (SMEAC) plus annexes | Full plan and orders |
| FRAGO | Down | Whenever the plan changes | Five paragraphs, only changes filled in | Amend the OPORD without reissuing it |
| SALUTE | Up | Each enemy observation | Six fields | Describe the enemy completely |
| SPOTREP | Up | Immediately, unscheduled | Short; usually a SALUTE line | Pass time-sensitive information fast |
| SITREP | Up | Fixed schedule | Standard headings set by the unit | Keep the higher picture current |
| 9-line MEDEVAC | Up | Casualties needing evacuation | Nine numbered lines | Get the right vehicle to the right place |
Where they fit in the wider system
These formats are the plumbing of command and control. SPOTREPs and SALUTE lines feed the intelligence picture, including the enemy ORBAT, the running estimate of who the enemy is and where. Changes in threat often show up in orders as new alert postures, such as a raised MOPP level or a stricter emission control condition; the scales themselves are compared in military alert levels explained. And every OPORD sits inside legal limits it can’t loosen, the subject of LOAC vs. ROE.
If you meet one of these terms outside a military setting, the same logic usually holds. A “sitrep” in a crisis team is the scheduled update. A “FRAGO” from a manager amends the existing plan and leaves the rest standing. The formats work because everyone agrees in advance where each piece of information goes, and that idea transfers to any team that has to act fast with partial information.
