- lst Squad, lst Platoon, B Company, 9th Shock Troops Battalion.
- Major Vaughan's command squad, callsign Sunray 1-1, is the lead element of
- Boomerang Company, the UNSC's most elite force of Orbital Drop Shock
- Troopers [though that's what they all say].
- UNSC Navy Medic.
- Petty Officer Gruss is the Navy combat medic assigned to Major Vaughan's
- command squad. A woman of [very] few words, the ODSTs make it their mission
- to interpret "Doc's" opinion of their shenanigans by analyzing her body language,
- sighs, rude gestures, and grunts of disapproval. This friendly harassment ends
- when combat begins, for Doc holds the lives of the troopers in her able hands,
- wielding biofoam and trauma packs across the squad's position with incredible
- skill and delicacy. So perfect is her timing in dealing with injury that it borders
- on the prescient, and squad members resign themselves to the inevitable if Doc
- appears near them during battle.
- In addition to her medical skill, Gruss has shown a remarkable talent for escape
- and evasion by avoiding the Marines' many and varied attempts to induct her
- into their ranks as an honorary Helljumper. This irks some members of the
- battalion, but even ODSTs are not crazy enough to risk the ire of a medic [and
- Major Vaughan] by pressing the issue. When deployed with the command
- squad Doc patches up the team's injuries with her medkit.
