The Top Secret Top Coat - S2-E29

Hogan Gives a Birthday Party - S2-E1
Continuity mistake: Hogan Gives a Birthday Party when the prisoners capture a German plane. When it is taking off, it is an English Lancaster bomber with a twin tail. As it is flying overhead, it is an American B-17 with a single tail. Finally as it is shown flying, it is a German FW-200 maritime bomber.
Continuity mistake: After Hogan leaves the airman in the tree, LeBeau jumps down, and looks up to tell the man it will be OK. When the camera looks at the man, you see LeBeau's legs and feet behind him.
Colonel Klink's Secret Weapon - S2-E28

Colonel Klink's Secret Weapon - S2-E28
Continuity mistake: During the inspector general's visit, Le Beau and Newark fall out with switched hats (i.e. Newark is wearing Le Beau's red hat and vice versa). In the next shot when in formation, they are wearing their own hats. (00:21:00 - 00:22:00)
The Great Brinksmeyer Robbery - S2-E18
Continuity mistake: As Kinch answers the question about the radio, he's in quarter profile to the locker with his shirt open. After the cut to a wider scene happens, he's turned toward the camera, and his shirt is half buttoned.

Praise the Fuhrer and Pass the Ammunition - S2-E19

Continuity mistake: During Carter's second meal, the napkin in his shirt comes loose and starts to fall. A second later, it's firmly in place in his shirt.
A Klink, a Bomb and a Short Fuse - S2-E8
Continuity mistake: Newkirk comes out of Klink's office with a code book, and passes it to Le Beau, who immediately holds it up and opens it. In the close up, Carter's hands bring up a book with a camera in it, and Le Beau brings the book out from his back and opens it again.
Continuity mistake: When Klink is talking to Schultz, his monocle is in before he bends down, missing when he's looking at Schultz, and back when he straightens up.
Continuity mistake: As Schultz is going to get checked out, Hogan and the boys stop him, and Hogan feels Schultz's neck. Schultz's arms are by his sides, then after the angle change, they're by his hips. Also, there's two men walking behind the group that weren't there a second before.

Continuity mistake: After Klink and Schultz chat, Klink offers him a cigar. When holding the box open, Klink's hands shift positions a couple of times.
Answer: Nimrod's actual identity was never revealed in the series. It was only known that he was a British intelligence agent. Nimrod was not Colonel Klink. Hogan had only implied it was him as a ruse to get Klink returned as camp commandant, not wanting him replaced by someone more competent who would impede the Heroes war activities. The term "nimrod" is also slang for a nerdy, doofus type of person, though it's unclear why that was his code name.

"Nimrod" is originally a king and hero mentioned in the Tanach and taken into the Bible and the Koran. His name is often used in the sense of "stalker," "hunter," and sometimes figuratively as "womanizer" as in "hunter of women." I've never seen it used to denote a nerdy person, and although I cannot disprove that connotation, I think given his role, the traditional meaning is more likely the intended one.

It's widespread enough that Wikipedia has an entire section on it: https://en.wikipedia.org/wiki/Nimrod#In_popular_culture
