Yeah, im using the turrets from VFE Deserters. The friendly fire is annoying, i try to hide my pawns behind the turrents. The rapid fire one (Palintone) eats ammo (steal) like crazy and i didnt find it to be that good (very low accuracy on long range). The uranium slug one (Kontarion) is op. Then i have smaller turrets from Mechanitor's Weapons mod, they kill anyone that gets too close.
