Lindsey was a member of the Vector Ghost Team, a team completely alienated from the normal Spartan program. Only a few high level Navy personnel ever knew of her, or her team's existence. Her team and was not made public in 2547, unlike the rest of the Spartan program. She was a smart and capable warrior, a Spartan III at that. What she lacked in combat strength, she easily made up with tactical ideas and ways to win every fight.
