I noticed that if you change the color of your team to green that with the surroundings of the map they give you for the multiplayer game you can really blend into the surroundings and into your own areas buildings if they are close enough. Especially with the rebels. It makes it much harder to for your enemy to attack what that cant see.

That tactic doesn't work, the green is a bright one and it stands out. A better color to try this is grey. I can't even find my own men usually.
