I'd love to see a mod that allows you to craft/place heavy weapons like miniguns on tripod-like stands where you can then walk up to them and use them much like you can use the miniguns inside vertibirds. It'd make defending your settlement much more immersive and fun.
I agree, I've been wanting this for a while. Settlers with machine gun embankments on top of guard posts
You'd definetly expect a group like The Gunner's fer instance to have "MG-42" nests on the perimeter of their bases. As it is they usually just have one or two weak turrets, and maybe a robot or two, not very good "defenses" really.
