Continuity mistake: Just before Carrie is told Brody is going to Bluemont Park, Carrie is shown re-watching Brody's welcoming ceremony on her laptop with the speech the Vice President gave and the speech Brody gave. The footage Carrie is watching on her laptop isn't the same as when the ceremony was broadcast earlier in the episode. The footage on the laptop has the Vice President saying "Sergeant Brody, you're a man who's endured a terrible ordeal" followed by Brody walking up the podium saying "Thank you, Mr. Vice President." But what was shown earlier was the Vice President welcoming Brody home, nothing along the lines of "Sergeant Brody, you're a man who's endured a terrible ordeal." Also, the length of time Brody spent walking to the podium and saying "Thank you, Mr. Vice President" has decreased when re-watching the ceremony on the radio - the actual ceremony showed Brody walking up to the podium for about 3-4 seconds followed by a 1-2 second delay before saying "Thank you, Mr. Vice President", but re-watching it on the laptop, Brody walks up to the podium and says "Thank you, Mr. Vice President" all within a split second of replying.

Continuity mistake: When Jessica and Dana are in line for the Gaucho Taco drive-in, Jessica has one hand on the wheel, yet a frame later, from a different angle both are on the wheel.
Continuity mistake: When Saul is at the terrorists' house talking to a neighbour, his arms are either falling down straight or bent, depending on if it is a front or a back shot.
Continuity mistake: SPOILER - When Brody and Carrie are in the car having sex with her laying down, the shots behind her head show a big amount of space in-between her head and the door, yet the front shots show it squashed against the door.
Continuity mistake: When Carrie and Brody meet at the bar, his hand's position is inconsistent between shots.
Continuity mistake: When Sgt Brody first returns to the US, he's seen in uniform wearing a sergeant's three chevrons with one hash mark, indicating at least 4 years of service. Later, he's a Gunnery Sergeant, with two rockers below the chevrons, plus two additional hash marks to reflect the eight years he was a POW. In the episode "Achilles Heel," Brody and his wife attend a swank Capitol Hill party, but his dress blues have only the three stripes and single hash mark. Throughout the series, everyone addresses Brody as "Sergeant" and never as "Gunny," which is the traditional reference for a Gunnery Sergeant. (00:22:00 - 00:28:00)
Continuity mistake: After David listens to the recording that Carrie made in order to leverage the FBI, in the closeup facing David as he says, "For what? The hope that this Imam will give you information that you don't even know he has," David's right hand is empty as he holds it up, but it cuts to the shot facing Carrie and David's hand is still up though now he's holding his pen.

Continuity mistake: Tom nails the notepad with the bullseye drawing onto the tree trunk, and when he fires at the target the notepad is nailed differently and the bullseye drawing is entirely different as well. (00:27:20)
Chosen answer: Everyone else calls him Brody or Sgt. Brody, and it probably became habit to her.

Can't get the source but I read that even the Producer responded to that. Stating that it was common practise for a military wife living in a military complex as everybody refers to their husband by their last name.
