Here is another one. Slow is smooth and smooth is fast I guess
The only thing I have to say about this is that if you are going to stop your stack while others clear out a hall/class (the two that went to the right), it's probably not a good idea to stop where the shooters bullets are going to fly. There are two perfectly good walls on each side to post up on until the others return, and as they return at least one of them should of had their firearm oriented towards where ever the smaller search team is returning from.
