- "Not a girl who'd retreat. Just not in her DNA."
- ― Knocker on Brownie
During the Lighthouse War, Brownie took part in various operations as a member of the IUN-PKF's Golem Squadron. She assisted in shooting down Erusean Air Force bombers over Fort Grays Island and halted the advance of Erusea forces in Scofields Plateau.
During Operation Dual Wielder, she was hit by an MQ-101 over the Chopinburg Rainforest, where she was ordered to retreat with Gargoyle 1 but was pursued by Mihaly A. Shilage. Mihaly engaged Brownie in a dogfight after shooting down Gargoyle 1, where she was ultimately shot down and killed.
