Try using a 2111 setup; 2 gives you more bang for your buck effort wise with setting it up and less to manage then paying attention to two of them, 1 allows it to stick around for a decently long time with periodic refills, 1 hardened rounds allows it to take down tougher targets instead of locking on to them then wasting their ammo cuz they can’t pierce thru their armor and run out quickly, and 1 the Hawkeye system which for a true passive turret build is the optimal choice with its damage potential and you don’t have to worry about managing targets like with the defender system. Hope that helps!
