All of the bits you get:
As you can see, you get 2 sandbagged buildings, 2 tents, 2 piles of barrels, 6 sandbag walls, 4 gun emplacements and 6 defensive mounds with sharpened pickets. Plus a flag.
Below is a quick attempt at a comparison shot using some of the 6mm Brit Para's I've been working, along with one of the ACAV's that I received in the same order.
For those of you who want to look at the components a little more closely, I've taken some more picks and put them in the Picasa album : http://picasaweb.google.com/scannablegoose/6mmTerrain#
