SO19 

The Specialist Firearms Command SO19 now known as CO19 is a Central Operations branch of London's Metropolitan Police Service.

The unit's role is to provide a firearms capability and support to the rest of the service, most of which is unarmed.

It is sometimes considered by the media to be London's equivalent to the SWAT units in the United States.

SO19 are already on their way to the shooting, we need to provide additional support

Conquestor's O1

A lifeless NPC who’s somehow always top of the leaderboard by bunking all studies and just riding Discord like it’s an Olympic sport.

Don’t bother challenging Conquestor's O1, dude’s a Discord ghost but always winning.
