Potential defensive assets.

Guys, I started making it but I need ideas and what you like and want to be in it, for those who don't know I'm making a castle/base fortification in slab6 for grownades. I thought about making 3 high and thick walls with a step so you could run freely without getting shot inside the castle/base with windows, a second floor and roof with room for AAs and helipads for the future idea of using this castel/base fortification in Version 1.0 where they will be helis.
