Factual error: At both funerals, everyone wears combat dress. Soldiers wear service dress (formal uniform tunic and trousers with collar and tie) to funerals. In fact, combat dress is all anyone ever wears in the series. The British Army has a variety of different uniforms. Combat dress is not worn all the time, especially not by officers or senior NCOs.
Factual error: Although the regiment at the centre of the drama is fictitious, its cap badge looks like nothing that which would be worn by a British regiment. It includes no crown and looks more like a German cap badge.
Character mistake: The brigadier wears a regimental cap badge. Colonels and brigadiers have their own cap badge.
Factual error: Eve and Jorn wear uniform most of the time. Although SIB agents (British Army detectives) do sometimes wear uniform, they most often wear civilian clothes, as do German police detectives.
Factual error: When the two officers salute in Iraq, they give a naval (or American) style palm-down salute, not a British Army palm-forward salute.
Factual error: The only person ever addressed as "Sir" is the brigadier, and then only occasionally. No other officers ever seem to be addressed in this way.
Factual error: When the man who ran down Olly made an emergency call and then hung up there would have been a record of the call and his number could have been tracked. The police would investigate if any emergency calls were made. And the emergency services would have informed the police even if they didn't. An incomplete emergency call in the hour/area a child went missing and no-one would have reported it? Yeah right.
