True she sucks at fighting, but then this is supposed to be an infiltration mission where they try everything they can to avoid fighting, so her being a bad fighter shouldn't be that much of a problem, if they don't fail at the main objective of not being caught.

And while her type of Take-Over is quite bad at fighting, it IS suited for infiltration. She can appear as a harmless animal and listen in on the enemy without being recognized as a Human.... in theory anyway.
