Arma Reforger Capture and Hold scenario IDs and setup

Capture and Hold is a team versus team mode in Arma Reforger. Two groups of players secure sites and hold them against each other. There are 8 official scenarios, each a different battle zone. To run one, set game.scenarioId to its ID and restart the server.

What the mode is

Bohemia describes Capture and Hold as a multiplayer mode where two groups of players must secure sites and defend them for as long as possible. It mixes deathmatch with the classic “capture the objective” idea. Each scenario has its own objectives and strongpoints, so teams have to use the terrain. It is quicker and smaller in scale than Conflict, which is a campaign over a whole island.

Capture and Hold started as the first official Workshop mod. Since game version 1.2.1 it is part of the base game, according to Bohemia’s Capture and Hold Setup page. Bohemia’s Server Config list also counts all 8 as official scenarios. You do not need to add a mod to the server to run them.

The scenario IDs

Copy the whole ID, braces and .conf included. The first column is Bohemia’s name. The second is the name the ArthOS panel shows in its Scenario list.

In the ArthOS panel

Open your server and choose the Config Editor tab.
In the Server group, find Scenario.
Pick one of the eight Capture and Hold entries from the list. The list holds 23 official scenarios, so scroll down to find them.
Choose Save. Saved changes apply after a restart, so restart the server if it is running.

By hand

Open config.json.
Set scenarioId inside the game block:

{
    "game": {
        "scenarioId": "{9405201CBD22A30C}Missions/CAH_Factory.conf"
    }
}

Save and restart the server.

Set the player limit with Maximum players (game.maxPlayers). See changing the player limit.

If it does not work

The server does not start. Check the ID character by character, or copy it from the table.
The log says Unable to read the mission header. The game cannot read that scenario. The ID is wrong, or it belongs to a mod that is not on the list. Pick a scenario from the panel list.
You see an old Capture and Hold mod on the Workshop. Its page shows version 1.0.8, built for game version 1.1.0.50, which is older than the built-in scenarios. The built-in IDs above are the ones to use.
The Scenario list does not show the entry you want. Paste the ID into the box under the list.
