I acquired some more trenches from Ironclad Miniatures when I was at Sheffield and recently finished painting them. The one problem I have is with the heavy weapon positions, which unfortunately are a bit too small for my bases to fit in. Therefore I purchased more of the half round positions so I could use them at front and back of the weapons. They also had some new items, a wooden and a concrete pillbox. Both are very nice, so I bought one of the wooden ones, but it still is a bit too small for my heavy weapons.

This demonstrates how I use the half rounds for my heavy weapons
I've now got enough trenches for two RF battalions, so hopefully I've enough
