Do you know your ACC from your AC-12? And what on earth is an OCG? Line of Duty is returning to our screens with a series rerun, kicking off with season one on Monday nights from August 2020.
Whether you’re a newcomer to this gripping series of bent copper-busting action, or you’re about to binge the show’s most recent, fifth season, you’ve been warned – each episode is littered with police jargon.
The jargon and acronyms can be tricky to get your head around – and not just for viewers, but for cast members too.
“You have to really work on Line Of Duty, because the language is very difficult and what you’re describing is usually very technical and detailed, so you can’t busk it,” Adrian Dunbar, who plays Ted Hastings, said ahead of season five’ release. “So it’s just a question of getting your head down.”
Keeping track of all the acronyms they throw in is no picnic, especially since Line of Duty is sort of based on a real story, so we’ve done up a handy guide – check it out below.
The first-ever episode of Line of Duty is set for a TV repeat on Monday 3rd August 2020 on BBC One. Tune in before heading over to our cast aftershow Q&A.
It’s hard to keep up with police ranks and what they mean – Kate Fleming has gone from DC to DS to DI in the time we’ve known her. The below list is in hierarchical order:

DS – Detective Sergeant
DI – Detective Inspector
DCI – Detective Chief Inspector
Det Supt – Detective Superintendent
DCS – Detective Chief Superintendent
ACC – Assistant Chief Constable
DCC – Detective Chief Constable
