I developed a great and urgent need for obstacles when I read that if I'm defending in a mission with Prepared Positions, then I can deploy minefields and/or barbed wire with my Pioneers. Which, let's be honest, is pretty awesome. There is a Finnish Fortified Company in Rising Sun, which I want to have the option to run. So, here we go!
To start, I cut a thin piece of bass wood from a crafts shop into 2"x 8" sections, as that's the "Battlefront official" dimensions of obstacles. I drilled a bunch of holes in each so I had some flexibility in where to put posts. Primarily this was to make my barbed wire stand out from the minefields. My inspiration for the tangled mess came from this image:
Since I was using non-cotton sewing thread for my wire (I have a spool of hanging wire around here somewhere), I wasn't able to do coiled wire. I can do another few pieces with coiled wire if a) anyone wants to see how that's done and b) I can find that damn wire! At any rate, I put my "wire" on before applying flock. Big mistake! I highly recommend not obstructing your ground surface until you're satisfied with it.
The sign is from a PDF Battlefront has on their website. Linky here.
I have only really completed one minefield and one barbed wire obstacle. They need to have a few bits of flock plucked from their wires and their posts drybrushed (I believe a dark brown base drybrushed with Green Grey does the trick).
