Mjohnson, on this page, you can see my German Stronghold I built.

Go to "Mark's German Armor" Album, and at the very bottom is a picture of my stronghold.
I wish I could get better closeup shots of it, but my camera cannot handle it. I used alot of extra parts, small models and soldiers to show a stronghold that has just been called to alert status against a possible attack; even as a supply truck had arrived, and a couple of motorcycle scouts were being sent out.
I simply used Pollyscale acrylics and some Testors enamels to paint and drybrush the base, and used Elmer's Glue thinned 50-50 with water to glue on the grass and gravel/rock to the base. I used Elmer's full strength to glue down the moss that represents bushes. The troops, furnishings, weapons and other accessories I glued down with CA glue. All the motorcycles, vehicles, guns and equipment is loose, so I can change things whenever I want to.
I hope this helps with a few ideas for you.
