Corporal Sarah Holden is a young, spirited raccoon member of the Interstellar Republic's elite Stille Geisters special operations force, who plays a significant role in the "Operation Cold Snap" boarding operation on the massive Alliance flagship Leviathan. Holden is proficient with encryption crackers and later uses it on an access shaft hatch lock during the mission, working diligently to open it. Despite her nerdy nature and diminutive height, she's brave and volunteers to be first in most situations, and she's competent with piloting heavy duty Long-Wei class power armor, along with the use of a wide variety of weapons.

Here we see her in a interface under-suit, a form-fitting garment that not only provides thermal management and comfort inside the large battle armor, but also is a sophisticated MMI rig, allowing her to control its movement with incredible finesse, even in tight confines.
