Mother of God, there’s a lot of acronyms and initialisms to be learned when watching Line of Duty, isn’t there?
With the show’s sixth series reaching its hotly-anticipated climax, fans have spent much of their time Googling the acronyms that Ted, Kate and Steve use on a very regular basis – potentially just to confuse us.
In the gripping first episode, for example, we saw police officers talk a lot about a Chis. Short for a Covert Human Intelligence Source, these individuals – also known as ‘spy cops’ - secretly use relationships to gain information about a person.
Yet that isn’t the only acronym or initialism thrown about by the coppers in the BBC drama, and with a two-year gap since AC-12’s (Anti-Corruption Unit 12) last outing, we could probably all do with a refresher.
So, if OCG and MIT leave you confused, then our detailed list of the hit crime drama’s abbreviations may be able to help.
A handy guide to those pesky acronyms in #LineOfDuty for you, fellas. https://t.co/s5lA747gCf

It isn’t just acronyms and initialisms which can leave Line of Duty fans scratching their heads, either.
For those wondering what the status codes mean, status zero translates to an officer needing urgent assistance, status five means an officer is en-route to an incident, while status six means they’ve arrived at the scene.
Ten-eight is used when an officer is in service, while status 11 is used when they are off duty.
As for the Osman warning, which Kate mentions at one point during the series, that concerns a warning which police issue civilians when they are aware of a threat to their life.
With another series now underway, it’s likely that we’ll have even more phrases, codenames and more to add to the above list.
The final episode of Line of Duty , season six, airs Sunday, 9pm, on BBC One.
