I have to tell my wife that one. 
I was referring to the "muzzle flashes" of the turret where the droid should be (on the top behind the cockpit). It appears to be firing the blasters (couldn't think of the correct term in my last post).
I didn't even notice a turret up there until you said something. Wow, that just slipped past me. I think that one is an Ion cannon. The flashes do look kind of blue to me.
First time anyone has ever asked me thatI have to tell my wife that one.
But seriously. NavyDawg you have done so much to help out the Star Wars mod/scenarios that I can't thank you enough. Your units are just awe inspiring. If I was more computer savvy I would try to create units myself because you're just so inspirational. Salutes to you NavyDawg!!
.Thanks to all for the comments.
I did add the turrets to the two Naboo ships (where a droid would normally be). Not making a true Star Wars mod, I have taken a few liberties with Star Wars models. I still think they could pass as Star Wars units though.
