Led by Lieutenant Colonel Walter N. Cardwell, the Fade Cell is considered the top-tier unit of the Delta-4 Division, composed of veterans of hundreds of covert operations. The cell itself was divided into a small number of two-man detachments stationed on strategic points throughout UNSC space awaiting activation. Laszlo-108 was attached to this cell after his induction into Project LEONIDAS. Despite this, it failed to keep up with Halsey's SPARTAN-II platoon, a source of contempt for Admiral Rich.
