They're just standing there in the open against a enormous killing machine with no fortification at all. What are the odds that they survive? Pretty damn big if we're going by the rest of this arc's standards. It'll just get ridiculous if the army can overpower the Juubi so easily.

Oh, and if by some miracle the bad guys actually pull it off, I hope there isn't a cop out of revive-planet-jutsu from the 10 tails when Obito comes around. Blegh, I hope I'm wrong but this arc has been so predictable already.
