A mod I made for Fallout 4 back in 2017. There were no military themed defensive positions in the base game so I decided to start making them. Some things to fortify settlements and outposts with. I kitbashed existing game models to make defensive positions, concrete bunkers, trenches, obstacles, and tons of structures made out of sandbags. All textures were reused from the game, I also made some meshes from scratch.

Many things were modular and had snap-points to allow walls or entire trench systems to be formed. Things could also be sunk into the ground to account for uneven terrain.

Big thanks to Ethreon for making the collisions.
