Character mistake: The Captain yells to Tex to man the "Fifty cal" but Tex goes to a mounted M240 7.62mm weapon.
Extinction - S4-E1
Character mistake: Happy determines that the nitrogen hydroxide ate through the drum because it was "steel alloy," in contrast with Walter's requirement that it be "pure steel." These terms are inaccurate, and would not be used by technical experts like Happy and Walter. Every steel is an alloy, combining at a minimum iron and carbon; steel with other alloying agents is called "alloy steel," not "steel alloy." Because steel doesn't refer to one specific substance, "pure steel" could never be used to specify a material for a given application.
Character mistake: When Henry is speaking to the detective involved in investigating his father's death, the detective says that based upon evidence found at the house he requested a toxicology screen, which showed that his father died of a barbiturate overdose. He continues to explain that he found an empty bottle of hydrocodone in the bathroom trash can. Hydrocodone is an opiate, not a barbiturate. (00:07:35)
Character mistake: Doc holds the binoculars the wrong way round. (00:30:20)
The Battle of Central Park - S3-E6

Character mistake: When Ruzek and Voight are questioning Wade Henslow (the father of missing girl) at the station, after finding out he lied and set up his own security to find his daughter Adam looks at Wade Henson but addresses him as "Mr. Larson" which is actually the last name of one of the kidnappers they found DOA who got into the gun fight with his security guy, the ex-cop Kenny. (00:21:26)

Character mistake: When Jack and Kate are in the car discussing the fact that the Russian agents found him because of Mark Boudreau, Kate wrongly refers to him as Martin Boudreau.
Character mistake: At the end of the scene in the grocery store when Rachel collapses and people run to her aid, the camera pans out to reveal a sign that prominently reveals a sale on "Pop Tards" or possibly "Pop Taros."
Character mistake: Bellamy calls Monty "Murphy" when they get back to the Arc and he is losing oxygen.
Character mistake: Deputy Olmstead says to Lorraine Lyon, "You think that you're rich 'cause you're better than me." Surely, the line should have been "You think that you're better than me 'cause you're rich."
Suggested correction: No, she actually does mean Lorraine thinks she is rich because she is better than her. And to her, anyone who is not rich is therefore less, or else they would be rich too. It's the same type of thinking but with a different approach as what you suggest. It's about privilege.
Interesting. I can see it either way. Thanks for the thought.
Character mistake: When Billy Bones gives himself in to the redcoats, he states he is Long John Silver. In one of the next cuts, he talks about Silver in third person. The governor shows no shock and they keep talking as if Billy Bones had said at the start of the conversation who he truly was. Then he instructs the governor on how to take on "himself" and Flint.
Character mistake: At Houdini's performance for the Kaiser, a German officer with the rank of Lieutenant Colonel (Oberstleutnant) is asked to assist. Houdini at first correctly addresses him as Lieutenant Colonel, but then incorrectly refers to him as Lieutenant several times after that.
Character mistake: The brigadier wears a regimental cap badge. Colonels and brigadiers have their own cap badge.
Character mistake: Dr. Winter as a private in the Army says he'll probably 'go to the brig' for what he is doing. Brig is a Navy term, stockade is the Army term for jail.
Episode #6.4 - S6-E4
Character mistake: The character pretending to be Lt. Ellis refers to himself as First Lieutenant. That rank is referred to orally as "Lieutenant", not "First Lieutenant."
One Good Man - S3-E6
Character mistake: After Patton's ex-wife pushes him off the balcony and he lands on the researcher with the gun and the rest of the team come in, someone asks him if he is OK. He says that he is fine, nothing is broken. Other than his arms, ribs or neck how is he going to know that? He is already paralyzed. He can't feel anything.
The Prison Prep School Murder Case File 1 - S1-E10
Character mistake: To show how hard the top students are working at the prep school, we see one of them writing; "I was at the course of a eight-week intensive." (00:04:50)
