In a fourth season the Chief and Max get kidnapped by KAOS and eñd up in a New Jersey-located concentration camp run by Zigfried and Schtarker. A couple of points.

1. Fine character actors Johnny Haymer and attractive Kathie Browne fall in this ep as two KAOS agents we never saw before. Plenty of that on this show. However, she gets arrested by Max and he ( Haymer) is shot, I believe, dead by her by accident. So no continuity problem we do not see their characters again.
2. The concentration camp has guards in Nazi-like uniforms. Since when did KAOS ever have uniformed guards!?! Who in blazes were these guards? Did they outright even work for KAOS or some other agency? It would have been good speculation by the Chief to wonder to Max and other prisoner Control agents as to just who these guards really were.
3. Was this set the same set as Hogan's heroes?
