to your question
Asthetik,
I think there are like 2 or 3 Interlocking pieces on this map to create some bridges or smoother walls, but not too much.
I had an original map based on Damascus without an aerial vehicle, and the dunes provide sniper cover a tad too well. The vehicle allows a check on that problem. Also there are tunnels, a missile pod, and a laser to counteract the vehicles. So that's the reason for the Banshee.
I hope this adds some insight to the map itself and be sure to check out Middle District and Damascus as well!
