Who is Anna Lascher - The Medic from See How They Run and what is their importance?

Anna Lascher is code-named the Medic. She plays the part of tourist with Marc Jacobson, blending into the environment easily and aiding in the purchase of small arms and munitions. Later, she aids in the seizing of the Olympic Village and helps to corral and guard the athletes they have taken hostage. When Alix and David run into Anna on the way down to turn off the generators, Anna calls Alix a traitor, and was raising her rifle to shoot Alix when Alix used her Baretta to shoot her in the shoulder. Alix tries to make her understand, and tells her to think about what is happening, but Anna has been well-trained. She was not one of the survivors of this vengeful plot.
