Dedicated Fighter Doctrines

Dedicated Fighter Doctrines adds a target-role layer to X4’s existing fleet commands.

The normal wing assignment still controls how ships behave — Intercept, Bombardment, Attack Targets in Range, Protect Position, carrier operations, formations, docking and combat movement all remain handled by X4 and compatible AI mods.

FCD controls what classes of ship that unit is allowed to engage.

For example, a Fighter Screen can be restricted to S-class targets, while an Anti-Capital / Bomber group can be restricted to L and XL targets.

Clearing a doctrine returns the ship to normal X4 targeting behaviour.

The aim is to give players more control over fleet roles without replacing X4’s combat AI.

Extract the included:

X4 Foundations\extensions\The final structure should look like:

X4 Foundations\extensions\Fleet_Combat_Doctrines\content.xmlInstall the Nexus/local versions of the required dependencies listed below.

Do not install the Steam Workshop and Nexus versions of Dedicated Fighter Doctrines at the same time.

If removing the mod, it is recommended to clear active doctrines first, save the game, exit X4, and then remove the extension.
