Corrected entry: When hit-girl is pinned down late in the film by the few remaining men and is out of ammo, she never uses the grenades strapped to her. Assuming they were any kind of functional grenade, i.e. a flash, smoke, or frag, she could have used them to, at the very least, cause a distraction well before the guy goes to get the bazooka.

Correction: There are two reasons to explain that. The first reason is that she simply didn't think of it. The second reason is that she did think about it, but could not see how it would help in that situation.
