The Spear anti-vehicle Phalanx turret. I've gotten it into the game and crew-able. Not worked on it's damage and such yet. Having a bit of an issue sorting out the way it takes damage too, as right now it's indestructible and just the person manning it gets killed but these are still early stages so I'm sure I'll work it out.
