Core Mod System
How the 17th Pathfinders manage Arma 3 mods for operations.
A Core is a single Steam Workshop item that bundles every mod required for a specific mission set, era, or theme. Subscribe to the Core for the week and the Arma 3 Launcher pulls everything else automatically. Each operation announcement specifies which Core to load.
Setup Procedure
Unload Everything
In the Arma 3 Launcher, click Unload All in the Mods tab.
Load the Core
Enable the Core specified in the op announcement.
Subscribe to Dependencies
The launcher will prompt you to subscribe to any missing mods. Let it finish downloading.
Verify
Unload and reload the Core to confirm. Do this several hours before the op.
Approved Client-Side Mods
You can load approved client-side mods alongside the Core (HUD tweaks, audio, visuals). Anything not on the approved list risks an auto-kick on join from the server blacklist.
Approved Client-Side Mods Collection

Currently in rotation. Retiring Cores are still usable but no longer receiving new missions. If storage is tight, just keep the Cores you actually attend.
Active Cores Workshop Collection
Subscribe to all currently in-development active Cores in one go. Not every Core listed on this page is in the collection.
Open Collection
These Cores aren't in current rotation but are kept here for reference. You can still load and explore them, but no operations are scheduled.
