I was a little worried about the flock on the hills as it looked a little dark on the website but I'm quite pleased with how they look now they've arrived. I also wasn't certain if the bridge would be wide enough for tanks to cross but as you can see from the picture below tanks fit on the bridge fine.
The hills come pre-painted and flocked but you can buy them without flocking if you prefer. They also offer a desert finish if you don't want green. I give them 7/10, they're not brilliant but they do the job and I'd buy more if I needed them.
