I also liked the old TV show “Combat!” where they said, “Checkmate, King Two, this is White Rook, over!”
Yeah, “Checkmate King Two, this is White Rook, over!’’.
I'd venture to say some of the writers of that show were WW2 vets and that phrase was probably one some writer remembered as a soldier. "The Wild, Wild West'' was another one of my favorites.
The show “Combat!” is on over the air TV every Saturday night at 9PM ET on the “H&I” network. Several episodes are also on You Tube.
