Corporal Deborah Ogden, callsign "Ice Blonde" or "Ice," serves in the Mobile Infantry's elite Roughnecks A-01 Team, specializing in high-risk operations against the Arachnids. Her primary motivation is reuniting with her daughter on Earth after service, driven by her history as a widow. Her distinctive blonde hair is referenced by her callsign. Aboard ship, she moves comfortably with communal nudity in co-ed locker rooms, part of the military culture, and once deliberately used brief exposure to distract a fellow trooper during a confrontation.
Ogden demonstrates resilience and combat competence during the Fort Casey evacuation and boarding of the compromised starship *John A. Warden*. Operating within Lieutenant Daugherty's squad, she engages Arachnids in direct firefights. Following significant casualties in A-01 and K-12 teams, she assumes protective duties for Captain Carmen Ibanez, guarding a critical airlock while others target the ship's engines and confront the Arachnid Queen.
Pragmatic and confident, Ogden dismisses concerns about fellow soldier Trig's solo infiltration, asserting Trig knows her role as "a big girl." She engages in flirtatious, controlled exchanges with Sergeant Ratzass, physically pinning him against lockers once to demonstrate her lack of intimidation, establishing a recurring dynamic between them. During downtime, conversations with squadmates reveal her background as a mother, mentioning her daughter and deceased husband, contextualizing her determination to return home. This personal history informs her perspective on loss, evident when toasting fallen comrades with the acknowledgment that "not all" good people survive, implicitly referencing her widowhood.
Ogden survives the mission alongside Mech and Ratzass after the successful destruction of the *John A. Warden* and elimination of the Arachnid Queen threat. The trio collectively pays respects to their deceased teammates, making her one of six primary survivors.
