# Arma 3: Beginner-to-Advanced Guide

A practical primer for Arma 3, the open-world military sandbox. It covers controls, infantry fundamentals, vehicles, the Eden editor and Zeus, the mods and modes people actually play, and how to join a unit.

*Researched September 2026, current as of Game Update 2.22 (SPOTREP #00120) and its follow-up hotfix (SPOTREP #00121). Live games change; check the linked sources if something differs.*

> Arma 3 is still getting official updates more than a decade after launch. Game Update 2.22 (August 11, 2026) brought MH-80 Ghost Hawks, new languages, and platform support; it also synced the experimental Mac port to the same version as Windows. Creator DLCs like **Western Sahara** and **Expeditionary Forces** keep getting their own patches too. Bohemia's newer game on the Enfusion engine is **Arma Reforger**, but Arma 3 still has the larger mod and mission library.

## Quick Start

1. **Play the Field Manual and the Bootcamp campaign first.** Bootcamp teaches the basic controls in context. The Field Manual (from the main menu) is your reference.
2. **Check your keybinds.** Arma uses a lot of keys, and the defaults are dense. Rebind anything awkward before your first multiplayer session.
3. **Get prone, stay slow.** One or two rifle hits can drop you. Move from cover to cover, and don't sprint across open ground.
4. **Zero your scope** (Page Up/Page Down) for long-range shots. The current zeroing shows in the top-right weapon info.
5. **Use the map (M)** constantly. Most combat happens at 200–800 m, and navigation is half the game.
6. **The action menu is the scroll wheel.** Opening doors, getting into vehicles, healing, and picking up items all happen through it. Middle-click or your Action key confirms.
7. **Manage stamina and weight.** Heavy gear drains stamina fast. Check your load in the inventory (I).
8. **Join a milsim unit or a well-run public server** for the best experience. Pub gameplay without communication falls apart quickly.
9. **Learn the Eden Editor.** Building your own training scenario is the fastest way to practice anything.

## Core Controls (Default)

These are common defaults. Check Options, then Controls, because presets can differ.

| Action | Key |
|---|---|
| Move | W A S D |
| Sprint (hold) | Shift |
| Crouch / Prone | X / Z |
| Adjust stance (fine) | Ctrl + W/A/S/D |
| Lean left / right | Q / E |
| Step over / vault | V |
| Free look | Alt (hold) |
| Optics / hold breath | Right mouse (tap/hold) |
| Zeroing up / down | Page Up / Page Down |
| Fire mode | F |
| Reload | R |
| Throw grenade | G |
| Nightvision | N |
| Flashlight / laser | L |
| Map | M |
| Inventory | I |
| Action menu | Scroll wheel, confirm with middle mouse |
| Voice channel cycle | . and , (period/comma) |
| Push-to-talk | Caps Lock |

**Tip:** Arma uses **weapon resting** (on walls or windowsills) and **bipods**. Deploying a bipod or resting your weapon greatly reduces sway.

## Infantry Fundamentals

### Movement and cover

- **Bounding:** one fireteam covers while another moves, then they swap. Even in pubs, moving with a buddy keeps both of you alive longer.
- **Use terrain.** Reverse slopes, ditches, and walls stop rounds far better than bushes. Bushes hide you but don't stop bullets.
- **Don't skyline yourself** on ridges. Crest them prone or offset.

### Shooting

- **Ballistics matter.** Bullet drop and travel time increase with range. Set zero to the target's range and lead moving targets.
- **Sway:** it goes up with fatigue, injury, and standing. Crouch or go prone, rest your weapon, and hold breath for precise shots.
- **Suppression:** incoming fire increases your sway. Return fire to suppress enemies in turn.

### Medical (vanilla)

- **First Aid Kits** heal you up to a limit in the field. **Medikits** and a medic (Medic role) can heal fully.
- Getting shot in the legs or arms affects movement and aim. Treat it quickly.
- Most milsim groups run **ACE3** medical, which is much more detailed (bleeding, tourniquets, blood, pain). See the mods section.

### Communication

- Voice channels: Global, Side, Command, Group, Vehicle, Direct. Use **Direct** for nearby chatter and **Group** for your squad.
- Most organized groups use radio mods (**TFAR** or **ACRE2**) for realistic radio behavior.

## Vehicles

| Vehicle type | Notes |
|---|---|
| Cars and trucks | Fast transport. Easy to kill with launchers and MG fire |
| APCs/IFVs | Troop transport plus firepower. Crew roles: driver, gunner, commander |
| Tanks (Tanks DLC improved them) | Deadly, but vulnerable to AT and to being isolated. Keep infantry nearby |
| Helicopters | Transport and CAS. Learn the flight model in the editor first (advanced flight model is optional) |
| Jets (Jets DLC) | Carriers, sensors, and targeting overhauls. Radar and data link matter |

**Crew tips:**

- In armor, the commander spots and the gunner shoots. Coordinate on Vehicle channel.
- Use the **sensor panels** (added in the Tanks/Jets updates) for radar and IR targets.
- Crashing a helicopter full of players is the fastest way to be banned from a server. Practice solo first.

## Official Content and DLC

**Main expansions and platform DLC:**

| DLC | Adds |
|---|---|
| Apex | Tanoa map, campaign, new weapons and vehicles |
| Contact | Livonia map, an alien-contact campaign, the "Spectrum Device" |
| Tanks | Heavy armor and a tank mini-campaign |
| Jets | Jets, a carrier, sensor overhaul |
| Marksmen | Marksman rifles, deployable bipods, weapon resting |
| Helicopters | Heavy transports, sling loading, advanced flight model |
| Laws of War | Humanitarian and demining content, plus a story campaign about the aftermath of war |
| Karts | Go-karts (a joke DLC that's actually fun) |
| Art of War | Art gallery charity content |

**Creator DLC** (third-party content published by Bohemia; release dates from arma3.com):

| Creator DLC | Developer | Released |
|---|---|---|
| **Global Mobilization: Cold War Germany** | Vertexmacht | April 2019 |
| **S.O.G. Prairie Fire** (Vietnam) | Savage Game Design | May 2021 |
| **ČSLA Iron Curtain** (Cold War Czechoslovakia) | ČSLA Studio | June 2021 |
| **Western Sahara** | Rotators Collective | November 2021 |
| **Spearhead 1944** (WWII) | Heavy Ordnance Works | July 2023 |
| **Reaction Forces** | Rotators Collective | March 2024 |
| **Expeditionary Forces** | Tiny Gecko Studios | November 2024 |

Western Sahara (update 1.1.9) and Expeditionary Forces (update 1.2.2) both got patches in September 2026.

The base game's **"The East Wind"** campaign spans the islands of Stratis and Altis. It's a good way to learn the game before multiplayer. The base game also ships official multiplayer scenarios: **Combat Patrol**, **Escape**, and **Warlords**.

## Popular Modes and Mods

### Multiplayer modes

- **King of the Hill (KOTH):** a big PvP server mode with persistent XP and unlocks. The easiest way to find action fast.
- **Antistasi (and variants like Antistasi Plus / Community):** co-op guerrilla campaign. Build up resistance on a map over many sessions.
- **Liberation:** co-op campaign to liberate the map sector by sector, with logistics and building.
- **Exile / Altis Life-style servers:** survival and role-play communities.
- **Zeus missions:** a Game Master controls the enemy live. Many units run weekly Zeus ops.

### Staple mods (Steam Workshop, managed with the Arma 3 Launcher)

| Mod | What it does |
|---|---|
| **CBA_A3** | A library that most other mods depend on |
| **ACE3** | Medical, ballistics, interaction menu, logistics. The milsim standard |
| **TFAR / ACRE2** | Realistic radio (with TeamSpeak for TFAR) |
| **RHS (AFRF, USAF, GREF, SAF)** | Realistic modern weapons and vehicles |
| **CUP** | Classic Arma 2 content and maps ported to Arma 3 |
| **Enhanced Movement** | Climbing and extra movement |
| **JSRS / Blastcore-style sound and effects** | Better sound and visual effects |

Load mods through the **Arma 3 Launcher** and use presets for each server or unit. Mismatched mods are the most common reason you can't join a server.

## Eden Editor and Zeus

- **Eden Editor** (main menu): place units, set waypoints, and hit Play. Great for practicing aiming, driving, flying, or AT drills.
- **Zeus:** the live mission control. In Eden, place a **Game Master** module and assign it to yourself to spawn units and run scenarios on the fly.
- **Workshop scenarios:** there are thousands of single-player and co-op scenarios for when you don't have a group.

## Joining a Unit (Milsim)

- Look for units on Reddit, Discord communities, and Arma unit-listing sites. Check their timezone, commitment level, and modpack.
- Expect an orientation or basic training (radio procedure, ACE medical, formations).
- Most units play weekly with a fixed modpack. Download it before your first op, since packs can run tens of gigabytes.

## Common Mistakes to Avoid

- **Running in the open.** You'll get shot from 500 m by someone you never saw.
- **Not setting zero.** Your shots at 400 m fall short if your scope is zeroed for 100 m.
- **Carrying too much.** Fatigue ruins aim and stops you sprinting.
- **Flying with a full helicopter before practicing solo.** Crashes kill everyone on board.
- **Joining modded servers without the right modpack.** Check the server's required mods first.
- **Teamkilling by misidentification.** Check your map markers and the tags your server uses before shooting.

## Advanced Tips

- **Use the rangefinder or a laser designator** to get exact range, then zero or adjust holdover.
- **Weight changes handling.** Heavier rifles and LMGs sway more and take longer to steady. Match your weapon to your role and ranges.
- **Use the IR laser with night vision.** It lets you aim without looking down the scope at night.
- **Plan routes on the map** with markers before stepping off. Good units plan more than they shoot.
- **Try the Advanced Flight Model** once you're comfortable. It adds torque, rotor physics, and autorotation.
- **Watch performance:** Arma 3 is CPU-bound. View distance and object view distance matter more than most graphics settings. On busy servers, performance is limited by the server's FPS.

## FAQ

**Is Arma 3 still being updated in 2026?**
Yes. Game Update 2.22 (with a hotfix after it) is the latest official build as of this writing. Creator DLCs also get their own updates.

**Should I buy Arma 3 or Arma Reforger?**
Arma 3 has the bigger mod, mission, and unit ecosystem. Reforger is newer (on the Enfusion engine) and runs on consoles. Many players own both.

**Is there a cheap way to try all the DLC?**
Bohemia sells an **Arma 3 Pass** on Steam, a time-limited pass that Bohemia pitches as a way to "try out everything Arma 3 has to offer" before buying. Arma 3 and its DLC also go on deep discount during Bohemia's regular Steam sales.

**Do I need DLC to play with friends?**
Not usually. Missing DLC content is often playable in a limited form on servers. Check server requirements for Creator DLC maps.

**What's the best mode for beginners?**
The Bootcamp campaign, then a KOTH or Antistasi server, then a beginner-friendly milsim unit.

**Why does Arma run so badly on my PC?**
It's heavily CPU-bound. Lower view and object distance, and check the server's FPS (low server FPS makes AI and vehicles stutter).

**How do I install mods?**
Subscribe on the Steam Workshop, then enable them in the Arma 3 Launcher. Save presets for each server or unit.
