Karl-Heinz Noak

The name matches Karl-Heinz Noak, an army lieutenant who led a platoon in the 2nd company of Panzer-Jäger-Abteilung 46, an anti-tank battalion. He received the Knight's Cross on 5 August 1940 and the Oak Leaves, a higher grade, on 16 January 1942. No further biography was found, so the match rests on the name and faction.
