Not sure how many vertexes I should use for the shield, but since you're likely to have a lot of units on the screen I kept it as low poly as I could (40 vertexes, 96 edges, 56 faces, when triangulated). @Lion: Can you make the texture? I've attached the UV-map to this post. You should make both front and back to this UV-map, they are exactly the same. Should I also give the hairy shield a try? Not sure how we're going to make it look hairy in the game though.
