One question: If Helen and Pauling are still around, why not the original canon classes? I don't see any of them to be the type to retire or go quietly into the night once they've outlived their usefulness. Also, the control of RED and BLU over the world seem to be a little bit more thorough than what you've depicted so far--I'd actually find it more plausible that they pluck their new Sniper straight out of the Taliban, since with the American government you'd have to worry about things like plausible deniability. (And if they complain about losing their best Sniper, just ship them some more arms. It's not like Mann Co. would be picky about their clients.)
