Aaron Motilla is a superb modeller who has built this gorgeous terrain. He is also a Skirmish Sangin fan. More of his work van be seen here although all in Spanish, Google translates a fairly good job and there are tons of great images to see what he does and how he does it.
More of his work can be sen below, he even has working street lights.
Way to go Aaron and thanks for sharing this on the Skirmish Sangin forum:
