Her name is Raisa (or Raissa, depending) Pöttgen. She's based, as far as I can tell, on Rainer Pöttgen the real Marseille's Wingman in North Africa.
Her familiar is a Shrike(a type of bird), and she flies as Marseille's wingman in the JFW Africa Corps. That's about as much as I can effectively pull from her bio without guessing.
