RADIO CALLSIGNS

From the perspective of control, each unit is represented by an LSPD-specific callsign. Typically, a callsign is made up of three elements: the division number, the unit type and the "beat" number. For example, division 1 is LSPD, an "A" is patrol unit with two officers and their patrol vehicle number can be a number like 211. Such a unit would identify themselves as 1-A-211 (or 1-Adam-211, using the LSPD phonetic alphabet). Patrol Vehicle numbers will be assigned to you by a superior officer. There are several patrol types:

A: Two officer patrol unit ("Adam")
D: SWAT ("David")
L: One officer patrol unit.
M: Motorcycle unit
C or "cycle": Bicycle unit
