That is a very visible cameltoe on her; with a little paint thinner, it should be possible to just give her crotchless panties, since it looks like that slit is already sculpted on.

>Also what is the big tank thing for?
Well, her rifle at the very least seems to have a milk phial plugged into it, so her weapons presumably just shoot milk. If that's the case, then the big tank must be her extra ammunition - she milks herself into the tank, and refills her guns as they run low. Looks like there's a port on the side of the tank, so there may be a tube that connects from it to the bottom of the rifle that we're just not seeing in the promo shots.
