Biography
During the outbreak of the Lighthouse War, Major McOnie, along with Warrant Officer Lehmann and a contingent from the Osean Army focused their efforts on restoring one of Stonehenge's railguns. This was undertaken in order to destroy one or more of the Arsenal Birds, which were shielded by a microwave powered forcefield.

On August 19, 2019, they were able to get it fuctioning, setting in motion Operation Dragon Breath.

During the mission, Major McOnie expressed impatience at the slow rate that the cannon was powering up. She became desolate when it was discovered that the survey team had been killed. However once Warrant Officer Lehmann gave her the idea of aiming Stonehenge via eyesight, she quickly recovered and devised a calculation to shoot down the Arsenal Bird with the help of range tables left by the previous occupants of Stonehenge.
