That's right people turrets that are made from multiple section and is bigger than any of the weapons you will ever find. But first I will tell you about dymanic turrets.
Dyamanic turrets are a combination of drivered sections and link weapons (and may inculde triggering) to form one big targetting weapon. These may range from very big to itty-bitty. What are dymanic turrets good for then? Aside from looking nifty, its also perfect for dogfightings as the whole section is moving along with the Turrets. Here's an example of a heavy fighter equiped with 2 triple-autocannons and 2 crystal cannons.
Here's it is idle;

But once it spots its targets, the turrets track independant from each other like this.

Oh but you ain't here to see small sized turrets right?
Well I present to you my very own Heavy gattling cannon! (The bullet belt does rotate, problem is I don't know how to make GIFs ;cry;)

And to prove that it actually works, here it is in action!

It's fully functional, if you need it in your ship, load up the file, rename it to whatever you want, set the field to what ever you want and then clone group the master. The master section here is the defualt stock section 13.

(Bear in mind that weapons are secondary to the design of my ship, if there is a long period of time where I don't make new weapons, its because I'm too busy making my own ship!)
