"The anti-personnel phalanx turret's rapid fire capabilities allow it to excel at the suppression of enemy infantry."
you ever saw a bunch of Infantry being shot at by the Xiphos? They can't do anything because they are laughing their *** off over you trying to hit them. Tough i got 3 kills with it after 4000shots.
Not only do the anti-infantry turrets suck, they're exceedingly rare. I think I've found... 2(?) of them after about a year's worth of play.
