This coming weekend it's a replay of Stalingrad (link to previous game) and I'll be playing the Germans this time. My only contribution to the game is a Stuka, but I decided to make a couple of "Urban ruin" flying bases to take along as well. The construction is old CDs for the base and Plastic Padding filler mixed with stones to support the magnetic retriever. I then added some old walls and other scatter and painted it black. Dry-brushed with grey, terracotta red and a touch of sand they give a reasonably ruined feel.
The lower surface is a couple of 88p mats From Wilko that I used for ploughed fields
