How do I install Arma 3 mods on my server?

Upload the Workshop folders through the panel file manager or over SFTP, then add each one to your server's startup parameters. Copy bikey files into the keys directory if you verify signatures. Server-side mods can be listed separately, and the live console shows exactly which addons loaded when the server starts.

Can I run a headless client for AI?

Yes. Unlimited player slots and unmetered allocations, 10 by default, mean a headless client costs nothing extra beyond the CPU time it uses. Launch it against your own server address to move AI processing off the main simulation thread, which usually smooths out large infantry engagements and convoy missions.

How do I upload my own mission files?

Drop the PBO into the mpmissions folder using the file manager or SFTP, then add the mission to your rotation in server.cfg. You can edit both from the panel without downloading anything first. Automatic daily backups keep 10 rolling copies, so an edit that breaks the cycle is quick to reverse.

Which location should my unit pick?

There are 5 game-server locations: Miami, New York City, San Jose, Toronto and Brussels. European units usually sit best in Brussels, while mixed transatlantic rosters often compromise on New York City or Toronto to keep desync low.

About Arma 3 hosting

Running an Arma 3 Milsim Unit

Arma 3 units live and die by their server. Missions run long, AI counts climb, and a stutter during a breach ruins an evening of planning. An FSH server gives you a persistent box you control: set your slot count, load your mission cycle into mpmissions, and keep the same address week after week so members can save it in their launcher favorites.

Because setup is automated and instant after checkout, you can be testing a mission the same hour you order. The task scheduler handles nightly restarts before an op, and automatic daily backups keep 10 rolling slots of your mission files and profile folder in case a config change goes wrong.

Loading CBA, ACE3 and Workshop Mods

Mod sets are the heart of Arma 3. Upload Workshop content through the file manager or SFTP, reference each folder in your startup parameters, and keep bikeys in place so signature checks pass. The panel keeps a live console for watching the load order resolve, and the one-click version changer lets you match a branch when a mod lags behind a game update.

Server-side additions such as logistics or performance mods sit alongside client-required sets without extra cost. Unmetered ports and databases, 10 of each by default, cover a headless client, a TFAR relay and any stats backend your unit decides to run alongside the game.

Choosing RAM for AI-Heavy Missions

Vanilla Arma 3 with 20 players is comfortable on 6 GB and three cores. Add CBA, ACE3, RHS and a few hundred AI and memory use climbs fast, which is where the 12 GB plan and its five cores earn their keep. Large public or campaign servers running 60 or more slots with headless clients are best on 16 GB or 24 GB at a flat $2.50 per GB.
