Infantry Callouts & Phrases
A reference for common (and less common) radio callouts, brevity terms, and phrases used in our operations. If you’ve ever heard something on the net and had no idea what it meant, start here.
This is a working glossary tuned to our community - not a verbatim copy of any single military publication. Where definitions are simplified for clarity, that’s deliberate. If you want the deep version, links to source material are at the bottom.
How to read this guide
- CAPS = the actual word said on the radio.
- Italics = what it means or how it’s used.
- “Wrong / Right” pairs show common mistakes new players make.
- Examples assume a generic modern infantry context. Adjust to fit the mission.
Part 1 - Common Phrases (Everyone Must Know)
Prowords (radio basics)
These are the universal building blocks of radio comms. Get these wrong and everything else falls apart.
| Proword | Meaning |
|---|---|
| OVER | I’m done talking, your turn to respond. |
| OUT | I’m done, conversation ends. (Never “over and out”.) |
| ROGER | I received and understood your last transmission. |
| WILCO | I received it AND will comply with it. (Implies ROGER, so don’t say “roger wilco”.) |
| COPY | I received your transmission. |
| AFFIRMATIVE / NEGATIVE | Yes / No. Don’t use “yeah” or “nope” on the radio. |
| SAY AGAIN | Repeat your last transmission. (Never “repeat/repeat last” - in artillery, REPEAT means fire the same mission again.) |
| STAND BY/WAIT | Wait, I’ll get back to you. |
| BREAK | Pause between thoughts in a long message, so the receiver can keep up. |
| BREAK BREAK | Urgent - I’m interrupting current radio traffic for something important. |
| INTERROGATIVE | I’m about to ask a question. |
| HOW COPY? | Did you receive and understand? Asking for a readback. |
| GOOD COPY / SOLID COPY | Yes, I got it clearly. |
| RADIO CHECK | Can you hear me? Standard response is “LIMA CHARLIE” (loud and clear) or “5 BY 5”. |
Wrong: “Yeah I got it man, anyway…” Right: “Roger, out.”
Contact Reports
The single most important thing infantry call out. Bad contact reports get people killed.
The 3 Ds - Direction, Distance, Description
The bare-minimum format when you spot enemy. Used immediately, before any formal report.
“Contact front, 200 metres, two enemy in tree line!”
- Direction: front / left / right / rear, OR a cardinal direction (north, east, etc.), OR a clock bearing if everyone shares the same 12 o’clock.
- Distance: in metres. Estimate if you have to - “close” (under 50m), “near” (50–200m), “far” (200m+) is acceptable in a pinch.
- Description: what it is - number, type, what they’re doing.
Wrong: “Tangos over there!” Right: “Contact left, 150, three infantry moving north along the wall!”
Clock vs Cardinal - when to use which
- Cardinal directions (N/S/E/W) work for everyone in the squad regardless of where they’re facing. Use these by default.
- Clock bearings only work if everyone shares a common 12 o’clock - i.e. inside a vehicle, or when a leader has set a reference direction. Don’t shout “contact 3 o’clock” to a squad in a 360° perimeter; nobody knows which way your 12 is.
Engagement Calls
| Call | Meaning |
|---|---|
| TALLY | I see the enemy / target you described. |
| NO JOY/NO EYES | I do NOT see the enemy / target. |
| VISUAL | I see the friendly you mentioned. |
| BLIND | I do NOT see the friendly. |
| EYES ON | I’m watching the target. (Less formal than TALLY.) |
| LOST EYES | I had the target/friendly but I’ve lost track of it. |
Common confusion: TALLY = enemy, VISUAL = friendly. Don’t mix them up. NO JOY (no enemy in sight) vs BLIND (no friendly in sight) follows the same logic.
Fire Commands & Weapons Status
These tell you when you’re allowed to shoot.
| Call | Meaning |
|---|---|
| HOLD FIRE | Do not engage. Hold fire unless you’re being engaged or about to be. |
| WEAPONS TIGHT | Engage only positively identified hostiles. (Default for most ops.) |
| WEAPONS FREE | Engage anything not positively identified as friendly. (Rare - used in declared hot zones.) |
| HOLD FIRE | Stop firing now, but stay ready. Reversible. |
| CHECK FIRE | Stop firing immediately - something’s wrong (friendlies in line of fire, ROE issue, mistaken ID). |
| CEASE FIRE | Stop firing, engagement is over. Often paired with safing weapons. |
| ENGAGE | Open fire on the designated target. |
| FIRE AT WILL | Engage targets as you identify them, no need to wait for further commands. |
Wrong: “Cease fire, cease fire!” (when you actually meant “check fire” because of friendlies in the way) Right: “Check fire, check fire, friendlies on the objective!”
The difference matters: CEASE FIRE implies engagement is over; CHECK FIRE means stop immediately for a reason that may resolve.
Reload & Ammo Status
When you reload, your firepower drops. If you’re a key shooter (AR, MG, marksman) you tell people. Riflemen don’t always need to call it - use judgement.
| Call | Meaning |
|---|---|
| RELOADING | I’m reloading right now. Cover me. |
| COVERING | I’m covering for someone reloading or moving. |
| UP | I’m back in the fight. (E.g. “AR up!“) |
| DRY | My weapon is empty. (Worse than RELOADING - means you ran the mag dry, not a tactical reload.) |
| LAST MAG | I’m on my last magazine. |
| BLACK ON AMMO | I’m out of ammo. |
| GREEN ON AMMO | I’m fully supplied. |
| AMBER / RED ON AMMO | Intermediate states - getting low. |
Standard pattern: “AR reloading, give me cover!” → teammate: “Covering!” → “AR up!”
Grenade Callouts
Get these wrong and you injure your own team. Three rules:
- Always call out before you throw.
- Outgoing and incoming are called differently.
- If in doubt, shout louder.
| Call | Meaning |
|---|---|
| FRAG OUT! | I am throwing a fragmentation grenade. Get behind cover. |
| SMOKE OUT! | I am throwing smoke. (Specify colour if relevant: “Red smoke out!“) |
| FLASH OUT! | I am throwing a flashbang. Look away / shut your eyes. |
| GRENADE! | INCOMING enemy grenade. Get to cover, NOW. |
| BANGING! | About to use a flashbang on a room/doorway (CQB). |
Wrong: “Grenade!” when you mean you’re throwing one. Half the squad will dive thinking they’re about to die. Right: “Frag out!” (outgoing) vs “Grenade!” (incoming).
Movement & Status
| Call | Meaning |
|---|---|
| MOVING | I am moving (usually to a new position). Pairs with “Covering!” from teammates. |
| SET | I’m in position and ready. |
| POSTED | I’m holding security at this position. |
| HOLD | Stop, stay put. |
| PUSH | Move forward / advance to the next position. |
| FALL BACK / BUG OUT | Withdraw to the rear. BUG OUT implies more urgency. |
| RALLY | Move to the rally point. |
| OSCAR MIKE (O.M.) | On the move. (We’re moving / unit is moving.) |
| CHARLIE MIKE/CARRY ON/CRACK ON | Continue mission. (Carry on with what you were doing.) |
| RTB | Return to base. |
| STAND TO / STAND DOWN | Go to full alert / drop from full alert. |
Common pattern (bounding): “Bravo team, moving!” → Alpha team: “Covering!” → Bravo gets to next cover → “Bravo set!” → Alpha: “Alpha moving!” → Bravo: “Covering!”
Friendlies & IFF (Identification, Friend or Foe)
| Call | Meaning |
|---|---|
| FRIENDLY!/BLUE! | I am a friendly - don’t shoot me. Shouted when approaching another friendly position. |
| FRIENDLIES LEFT/RIGHT/FRONT | There are friendlies in this direction - don’t engage that arc. |
| BLUE | Friendly forces. |
| BLUE ON BLUE | Friendly fire incident. |
| CHECK FIRE, FRIENDLIES! | Stop firing immediately, friendlies are in your line of fire. |
| CLEAR LEFT/RIGHT/FRONT | No friendlies in this direction - engagement OK from this angle. |
Casualty Calls
| Call | Meaning |
|---|---|
| MAN DOWN | A friendly is hit. Doesn’t specify dead or wounded. |
| MAN DOWN, [NAME/POSITION] | Specifies who. Always include this if you can. |
| KIA | Killed in action. |
| WIA | Wounded in action. |
| WALKING WOUNDED/AMBULATORY | Wounded but can still move themselves. |
| LITTER | Wounded, cannot walk, needs evac soon. |
| URGENT / PRIORITY / ROUTINE | MEDEVAC categories (see 9-line MEDEVAC below). |
| MEDIC! | Calling for the medic to come to your position. |
| CASEVAC / MEDEVAC | Unplanned Medical Evac / Planned Medical Evac |

Part 2 - Advanced
Standard Report Formats
Memorise the formats - they’re how command builds the picture.
SALUTE (used for sighting/contact reports)
| Letter | Stands for | Example |
|---|---|---|
| S | Size | ”Squad-sized element, ~8 personnel” |
| A | Activity | ”Setting up a checkpoint” |
| L | Location | ”Grid 047 318” or “200m NE of objective ALPHA” |
| U | Unit / Uniform | ”OPFOR regulars, woodland fatigues” |
| T | Time | ”Observed 1430 local” |
| E | Equipment | ”AKs, one PKM, one technical with DShK” |
Used before or after contact, not during - during contact, send a TIC (Troops In Contact) instead.
SITREP (Situation Report) - pushed up to higher
A brief on your current state. Format varies by SOP, but a common version:
- Location (where you are)
- Activity (what you’re doing)
- Status (ACE REPORT)
- Next intentions (what you plan to do next)
“Bravo SITREP: holding ORP grid 047 318, 100% strength, green on ammo, prepping to step off at 1500.”
SPOTREP (Spot Report)
Similar to SALUTE but for any noteworthy observation, not just enemy contact. Three lines:
- ALPHA: Who observed it (omit if it’s you).
- BRAVO: What was observed (use SALUTE format).
- CHARLIE: Actions taken and recommendations.
ACE Report
A quick after-contact check on the team’s state. Usually called for by the leader after an engagement, all measured by RED/AMBER/GREEN
- Ammunition
- Casualties
- Equipment
Team members respond in turn: “Alpha 1, Green, Green, Amber”
9-Line MEDEVAC
The standard format for requesting medical evacuation. Memorise the order - line numbers stay fixed even if a line is “N/A”.
| Line | Content |
|---|---|
| 1 | Location of pickup site (grid). |
| 2 | Radio frequency, call sign, and suffix. |
| 3 | Number of patients by precedence (A=Urgent, B=Urgent Surgical, C=Priority, D=Routine, E=Convenience). |
| 4 | Special equipment required (none, hoist, extraction equipment, ventilator). |
| 5 | Number of patients by type (L=Litter, A=Ambulatory). |
| 6 | Security at pickup site (N=No enemy, P=Possible enemy, E=Enemy in area, X=Armed escort required). |
| 7 | Method of marking pickup site (panels, smoke, flares, IR strobe). |
| 8 | Patient nationality and status (friendly mil, friendly civ, EPW, etc.). |
| 9 | NBC / terrain description at pickup site. |
Tip: Lines 1–5 are pre-contact info (sent first). Lines 6–9 are on-scene info (can be sent after).
Fire Types & Terminology
| Term | Meaning |
|---|---|
| SUPPRESSING FIRE | Fire intended to keep the enemy’s heads down, not necessarily to hit them. |
| COVERING FIRE | Suppressing fire specifically to enable a friendly’s movement. |
| MARKING FIRE | Fire to mark a target for someone else (often tracers for an MG or aircraft). |
| AREA FIRE | Fire spread across an area to engage suspected positions. |
| POINT FIRE | Fire directed at a single specific target. |
| GRAZING FIRE | MG fire kept low to the ground (knee-high or below) - devastating against infantry. |
| PLUNGING FIRE | High-angle MG fire that comes down from above (typically over a crest). |
| ENFILADE / ENFILADING FIRE | Fire along the long axis of an enemy formation - maximum effect for minimum rounds. |
| FPF / FINAL PROTECTIVE FIRE | Pre-planned defensive fire, “last line” against an assault. |
| MAD MINUTE | Brief, high-volume volley by Machine Gunners - usually for response to contact. |
Formation Calls
| Call | Shape | When to use |
|---|---|---|
| WEDGE | V-shape, point forward. | Default for open terrain - good 360° awareness. |
| COLUMN | Single line, nose-to-tail. | Tight terrain (woods, urban alleys), or when speed matters more than fire. |
| STAGGERED COLUMN | Two offset files. | Roads, where you want some lateral spread. |
| LINE | Side by side, all facing forward. | Assault into an objective - maximum forward firepower. |
| ECHELON LEFT / RIGHT | Diagonal line. | Flank security on one side. |
| DIAMOND | Box with point forward and rear. | 360° security, used during VIP missions. |
Calling it: “Alpha, form wedge, 10m spacing, axis north” - formation, spacing, direction of travel.
Movement Techniques
| Term | Meaning |
|---|---|
| TRAVELING | Standard movement, low threat expected. |
| TRAVELING OVERWATCH | Lead element moves, trail element keeps a small distance back ready to react. |
| BOUNDING OVERWATCH | Trail element holds in position covering while lead element moves; alternates. Slowest, most secure. |
| SUCCESSIVE BOUNDS | Same element always leads; the other always follows up. |
| ALTERNATE BOUNDS | Elements leapfrog past each other - the one behind becomes the one in front. |
| PEELING / PEEL | Break contact technique: rearmost shooters peel off one by one, retrograding past those still firing. |
Battle Drill Terminology
These are pre-rehearsed responses to common situations.
| Drill | Meaning |

|---|---|
| STACK | Line up on a doorway or breach point, ready to enter. |
| STACK UP | Get into the stack. |
| SET (in CQB) | I’m in position on the door / corner / window, ready to go. |

| HOLDING SHORT | Stopped just before a corner or doorway, waiting. |
| PIE-ING / SLICING THE PIE | Clearing a corner by stepping out in small arcs to expose only a slice of the unknown space at a time. |
| CLEAR | This room/sector has been checked, no threats. |

Bullseye / Reference-Point Calls
A way to give locations relative to a shared reference point (“BULLSEYE”), used heavily in aviation but useful for ground too if everyone briefs the BULLSEYE before the op.
“Enemy infantry, BULLSEYE 270, 4 clicks.” = enemy is bearing 270° from the bullseye, 4km out.
Time Terminology
| Term | Meaning |
|---|---|
| H-HOUR | The hour an operation kicks off. “H minus 30” = 30 minutes before kickoff. |

| ZULU TIME | UTC. Often used in orders to avoid timezone confusion. |
| LOCAL TIME | Time in the AO. Usually called “LIMA”. |
Common Confusions - Quick Reference
The mistakes I hear most often from new players:
- “Repeat” vs “Say again” - say “say again”. REPEAT means fire again, in artillery.
- TALLY vs VISUAL - tally is enemy, visual is friendly.
- Cease fire vs check fire - check fire stops shooting for a reason that may pass; cease fire ends the engagement.
- Frag out vs Grenade! - Frag out = me throwing; Grenade! = incoming.
- Clock bearings without a reference - don’t shout “3 o’clock” in a 360° perimeter. Use cardinal directions unless you’re in a vehicle.
- “Roger that, wilco, copy” - pick one. Roger or Wilco is enough.
- Contact reports without distance/description - “CONTACT!” tells no one anything useful.
- Reload without cover - never reload without telling someone.
- Stepping on transmissions - if you hear someone keying up, wait. Cutting them off means the message has to be re-sent, twice as long.
- Long transmissions without BREAKs - anything over ~5 seconds, BREAK so the receiver can catch up.
