Thad Luckinbill as PO Moritz
The only known client to “fire” Harm. Upon recommendation of Lt Mark Gordon (who H got acquitted for clipping a cable in Italy) he selected Harm as defense but Harms heart wasn’t in it and was doing a poor job.

Stephen McHattie as Gunnery Sgt. Ray Crockett
The Marines best sharpshooter who “burned out” on killing and had an agreement with his old COs to keep him doing training until discharged.
