Megyn Soone, a human female, held the positions of both lieutenant and commander of the Vandal squad within Saw Gerrera's Partisans. Saw noted that her abilities as a lieutenant and her temperament were similar to Steela Gerrera, and she shared his conviction that sacrificing oneself was acceptable to end the Galactic Empire's oppressive rule.
Initially leading the Vandal squad, she later achieved the rank of Lieutenant. Soone participated with Saw in the Assault on Dooma 4 during 1 BBY. This operation saw the Partisans endeavoring to obliterate an Imperial metal refinery, as the refined metals were destined for a top secret project undertaken by the Empire.
