It occured to me in this thread:

That plastic trench line terrain would be pretty cool. Plastic trench terrain would directly support WGA's most unique line (WW1). Plastic trenches would also be useful and popular for just about any 20th century war gaming and sci-fi gaming.
Inspiration can be taken from GW's "Wall of Martyrs."
Although with slightly less skulls.
GW's "Wall of Martyrs" is partially built from bodies. It would sadly not be unrealistic for a WW1 trenchline to have bits of skeletons and fresher bodies sticking out of the mud. A generic leg with hobnail boot sticking out would work for all theaters. (Trenches often changed hands and one could find a mix of dead in and about the trench).
The plastic trenches should be modular and capable of being built in different configurations.
Thoughts?
