Yep, that would work a treat for Vietnam or some such.
However, the Malayan jungle was a bit more involved, with several layers and very few tracks. It was also virtually sunless and had to be hacked through one foot at a time.
A bit tricky to model and to run a game through, unless I work out some clever way to make modular terrain bases with removable trees.
Or somehting along those lines.
I'm thinking a small table area (3' x 3'?) with modular terrain bits that can be swapped around to represent jungle, rubber plantations, streams, villages and camps.
It's a lot of work but it would look good if I pulled it off.
