The K4 Ketzer is the night-fighting variant of the PKA Konrad, and was built along the same lines as the PKA G4 Gucker, from which it shares many parts, including the night vision and IR sights and waste heat converters. Unlike the Gucker though, the Ketzer kept the side windows and as a result, was slightly less armoured than the normal PKA K. The Ketzer was issued mainly to commanders only, and not the regular troops.
