Attack on Sight – Beasts
This will work better if you give your men the "attack enemies" job.
This will cause your faction to attack members of most beast "factions" on sight. They won’t wait for your command, and won’t wait until they’re under attack.
No AI changes are involved, I simply made your faction HATE these "factions" so the vanilla AI will attack them. The current version doesn’t include any mod-added factions.
I don’t currently have walls up to verify this, but I believe this would also prompt turret users to fire on sight.
I initially made this to proactively deal with River Raptors, and decided to just attack everything. I figured others could use it too.
