I think I'm going with troopsofdoom also. It's perhaps not the most original angle or scenery, but in terms of figures, action and general atmosphere, it's definitely the one that comes closest to how I view this week's theme.

Runner-ups would be SIC DETH and Agent Viper with their brawling scenes. And frankly, I think Lava Boss' pîcture had something going for it as well. The fight in that one is a bit one-sided, and it could have used some muzzle flash effects, but otherwise, it's a very dynamic photograph.
