Old Occupations
Special Branch characters can be created using the Police Detective. Unlike the usual rules for British Police in a Bookhounds campaign they may take Firearms as an occupational ability due to their special training.
For an MI5 Babysitter who watches over the shop use the Military (Army/Marine) occupation.
