The ADVENT Turrets rely on the aliens' advanced automation technology, providing security emplacements to bolster their "peacekeeping" forces. Once we've gotten a look at their inner workings, we many be able to integrate the technology to improve our chances of fending off a UFO attack.
The turrets we've seen deployed by ADVENT throughout their various facilities and security check points are automated much in the same way the alien mechanized units are. A significant amount of time was likely spent developing the optical sensors and targeting system, which I expect Shen will want to thoroughly examine following the disassembly process.
We've run across the ADVENT turrets in a variety of places, mainly near security checkpoints and other areas they're trying to lockdown. Now we've finally gotten a chance to pull one apart, I can say with certainty that they are operating entirely on their own, with no outside controller or remote direction given.
As much as I would like to test the targeting sensors, Central and Dr. Tygan have both expressed their concerns about test-firing the system before we know how it discerns between friendly and hostile targets. Considering how close the aliens' position these things to civilian occupied areas, the target recognition software must be incredibly accurate, or incredibly basic, I wouldn't be surprised if the aliens were just flipping the switch and setting these loose on anyone caught in the firing radius. I'll have to see about setting up some kind of test environment. L. Shen
