Bohemia’s official scenario list has four scenarios on Arland: Conflict, Conflict: HQ Commander, Combat Ops and Game Master. Pick one, set its ID as game.scenarioId, and restart the server.
Arland is the small map. Bohemia lists it as 4096 m by 4096 m, with about 6.5 km2 of land. It holds a Soviet airbase and two towns, Arleville and Beauregard.
The four scenarios

What each one is for
- Conflict - Arland. The main multiplayer mode on the small map. Two sides capture strategic positions and hold them, inside their radio range. See Conflict on Everon for how the mode works; the tuning keys are in Conflict server settings.
- Conflict: HQ Commander - Arland. A separate version of Conflict. Bohemia has no wiki page describing it. Its 1.8 changelog treats it as its own scenario, with its own base layout changes on Arland.
- Combat Ops - Arland. Bohemia describes Combat Ops as cooperative play with dynamic objectives, focused on small team tactics. On Arland the players are Special Forces on sabotage missions behind enemy lines. See Combat Ops.
- Game Master - Arland. No planned events. One player, the Game Master, places units and sets objectives in real time. See Game Master servers.
In the ArthOS panel
- Open your Arma Reforger server and choose the Config Editor tab.
- In the Server group open Scenario. The list holds 23 entries. Pick one of Conflict: Arland, Conflict HQ Commander: Arland, Combat Ops: Arland or Game Master: Arland.
- Choose Save, then restart the server. The change loads when the server starts.
By hand
Set scenarioId inside the game block of config.json, save, and restart:
{
"game": {
"scenarioId": "{C41618FD18E9D714}Missions/23_Campaign_Arland.conf"
}
}If it does not work
- The server will not start. Check the ID character by character, or copy it again from the table.
- A fresh world every time. Saving is off, or a match ended. See persistence and save games.
- You want more than one map in turn. Use the Rotation tab, see scenario rotation.
