Matthew: Great dio. The building and figures are excellently painted.
My only comments relate to the tactics shown and I submit them to you for future reference and don't mean to pick on the dio; 1) The guys would be more closely stacked at the door, going down the stairs so everybody could get into the room quickly. Surprise is to their advantage (I also realize you might not have done this so as not to have to modify the figs for the stair). 2) the guy with the battering ram would not be first to enter as he'd lose the initiative switching from ram to gun. There'd be another guy who had the ram waiting for everyone else to go by him into the building first, then he would follow. (although perhaps you are showing the last guy to go in?) (or maybe the door was unlocked so he was able to set the ram down and didn't need it?) 3) The ram would have been layed off to the side in order not to trip the rest of the team coming up the stairs.
Again, well done on the dio and I hope you find my comments constructive. I really like the paint job on the building.
