Various mods walls are scattered about in Weaponry when they should probably all go in the Fortifications tab along with the vanilla and such other walls:

Dectorio dect-wood-wall, dect-chain-wall, dect-concrete-wall, and dect-concrete-wall-from-stone-wall are all in Weaponry, they should go in Fortifications.

Natural Evolution Buildings ne-living-wall and ne-living-wall-refresh are all in Weaponry, they should go in Fortifications.

Reinforced Walls acid-resist-gate, damage-reflect-gate, acid-resist-wall and damage-reflect-wall are all in Weaponry, they should go in Fortifications. Interestingly this mod has concrete walls but they are already in the Fortifications tab.

Rampant Arsenal mending-gate-recipe-rampant-arsenal/mending-gate-rampant-arsenal, reinforced-gate-recipe-rampant-arsenal/reinforced-gate-rampant-arsenal, mending-wall-recipe-rampant-arsenal/mending-wall-rampant-arsenal and reinforced-wall-recipe-rampant-arsenal/reinforced-wall-rampant-arsenal (recipes don't match item names, both need moving) are all in Weaponry, they should go in Fortifications.

AAI Industry steel-wall is in Weaponry, it should go in Fortifications.

Schall Tank Platoon's Schall-concrete-wall (yes S is cap'd), and Schall-concrete-gate are all in Weaponry, they should go in Fortifications.

Exact reason why I don't support the fortification tab. There are to many items that need to go their and to many edge cases.

Any chance of moving the things that are in there back and remove the tab then? Having them scattered around makes it easy to miss things.

One of clowns mods should have an option for that IIRC
