Okay, so I'll give you one of the 5-10 things I'm doing, since I'm sure it's been done.
Give all your jungle fighters full ghille suits, in order to do this, make your terrain first, then model a pattern that matches it. Use long grass, flock, static grass, wiring & pva & flock, covering the entire model, so only a few discerning features are visible such as the eyes, face, gun barrel, and feet. They may end up looking like a wookie, but it's still cool, so long as it's green, or whatever color you're going for, especially if it matches the terrain, since it's possible your opponent may not even see a few snipers you put in dense trees.
When your doing your ghille suit, model it from bottom to top, this will give it even layers, and you don't have to keep flipping it up, or letting it dry before moving on to the next one.
