How she and Bond meet:
Bond easily shoots the rifle out of her hand, and Bond is convinced that she is more of a victim.
How she helps save the day:
Bond and Kara go to Afghanistan to thwart Koskov, and she joins the Afghan resistance in a fierce battle against Soviet troops. She also manages to keep a cargo plane aloft while Bond fights the killer Necros.
