At 0:56 seconds I think that's Basil Poledouris on the right when he was an Extra Klingon. He was in two other episodes too, as a Red Shirt and perhaps a Nazi Guard if I remember correctly.
Fascinating Behind the Scenes footage provided by Deforest Kelly's Stand-in Billy Blackburn. Looks like they filmed a lot of that where they shot Andy and Opie going fishing for THE ANDY GRIFFITH SHOW.
