Lieutenant Commander Ashley Williams is a career military officer with the Systems Alliance. Born in 2158 to a military family, Williams enlisted directly out of high school, splitting time between Earth and hostile environment training on Titan. After earning numerous commendations early in her career, Williams became a platoon guide on Eden Prime, where she was the only member of her unit to survive the geth attack.
Williams then served as gunnery chief under Commander Shepard on the SSV Normandy and was promoted to lieutenant commander after the Battle of the Citadel. More recently, an Alliance tribunal called on Williams to testify about her experience with the Reapers.
