There no longer exists a difference in identifying units as one or two man cars with LASD, although the east end stations tend to carry over the old "King" car in their call signs for contract city cars (one man cars).
"Adam" normally just identifies a second car assigned to the same area.
"Boy" could mean bike, or it could mean yet another car in the same geographic area. Temple station used the B designator to identify their special assignment/problems and community relations deputies.
Charlie is always a captain. 280C, captain of Compton Station.
David, is usually the station desk/dispatcher 180David, Avalon desk/dispatcher. Temple used David for CSO's working the field, most stations designate those as Zebra units.
E and F, pick your poison, although most stations designated overlap cars as Frank units ( a car that starts halfway between shifts)
George, a station gang unit, or pick your poison.
Henry, supposed to be a mounted unit, or pick your poison, Temple used Henry as a second overlap car in the same area as another.
Ida, commander, goes back to when they were called inspectors
J, your guess is as good as mine, but they are out there
King, used to designate a one man car, still used mostly on the east end of the county, or at some stations to designate when a trainee is riding solo in the last phase of training.
Lincoln, lieutenant
Mary, motor unit
Nora, usually only heard to designate a night detective car such as 828N1, a detective working nights at Compton Station
Ocean, usually a security officer (SSO)
PaulEdward is parking enforcement
Robert is a reserve deputy
Sam sergeant
Tom, traffic car
Union, used to be utility deputy, but I don't know of any stations that still use a deputy in that spot.
Victor, civilian volunteer
some stations use Union and X-Ray to designate special overtime assignments, sometimes Edward too.
Young used to designate a unit that had a satellite phone, usually assigned out in the boonies somewhere.
Zebra is hard designated to denote a non department employee, such as Norwalk public safety that is allowed access to sheriff's communications. A lot of stations also use it to designate department CSO's assigned to work the field.
This is current as of my retirement in Aug of 2019
