She's the gunner in the Company Commander's truck---did the best on a test with the thing, which weighs more than she does.
She's in a situation she doesn't want to be in, accepting that she agreed to it but not happy about it---and it's a shitty situation. I mean, she's over there trying to get everybody to vote by absentee ballot and cast out the Bushies and all, but in the meantime they're getting shot at and having little kids try to handgrenade them.
If you're looking in, L.: hello over there. Hang in.
