someone should chek this since i dont have teh ep anymore, but i believe they said they would have trouble fighting them if they didn't use the seals, not that they'd be defeated.

seriously, y would they be chuunins? logically it makes no sense. how many actual chuunin characters do we know beside iruga? almost everyone else is jounin, and it makes sense that oro's "elite guards" who he sent to escort sasuke would be, well elite.
