Really rough "wouldn't it be cool if...?" and colour muckabout. For some reason I was thinking about special armoured suits that allowed soldiers to bury themselves and then pop up behind the enemy. I usually have a real hate-on for lights on armour, but I thought it might be a valid safety thing in this case (something about getting buried only to discover the popping up part didn't work XD), and given that the whole idea is pretty daft anyway it was the least of my concerns.
Not terribly happy with it, but at least the idea is committed somewhere and I can dig it up again at a later date.
Edit: Right, I think that looks a bit better... X3
