Whoa...truly a what-in-the-flying-fuck-is-going-on-match. Both sides decided to derp it out. I don't know whether this is an unorthodox pro/abuser or an incredibly lucky but forward thinking noob .
Not sure whether the US player was lucky or not. The initial bulding of TT's everywhere was thinking "out of the box" so to speak and the first upgrade was a mine-sweeper which is what most high level players would do. But any US player that goes T2 and relies on either Airborne or Rangers as his main infantry/fighting force deserves all that is coming to him.
