So I was re-reading the chapter again and noticed that even Sakura's base punch (which we all know at this point to be capable of obliterating landscapes) didn't do any damage to the Juubi soldier
Notice how the soldier is only pushed back and was preparing to counter attack.
Of course then Sakura goes banzai/power up and punches it even harder, killing it.
However, Sakura's base strength has generally been acknowledged to be fairly frightening, even by many of the other main and supporting characters.
So maybe she has a good "reason" for "fodderizing" the Juubi infantry.
Just a thought I'm throwing out.
