If you remember this building block in Arma 2, you're a legend. This building piece is far more useful than a handful of other recycled parts brought back from Arma 2, case and point being the H-Barrier Camo net Tower. That was less favorable than the Rampart, at least from my experience.
The rampart is great for everything. Also, it would look stunning with better textures, and for Tanoa, imagine that rampart with the wood side covered with vines and deep green leaves to camouflage it. Now THAT, would be a must have.
