The intent is to blow them up and take all the loot and scrap dropped by the structures.
Thank you for this information.
The storage containers will drop interesting loot depending on the distance/structure visuals.
I saw a lone laser turret by itself and was confused on why I couldn't loot it and basically acted as a glorified camera (no power, literally by itself). I took it out and it did indeed drop loot, as well as a different Outpost's warehouse that had no defenses just a bit north of it. Going further out provided more of a challenge, as expected.
They also provide a mild 3rd party crossfire feeling of aliens and outposts chipping away at each other while you get as involved as you want.
Hm, maybe I could do something with this information.
