Guild of Law-Shields
Each commander commands several captains who work to arrange shifts and patrols, as well as active investigations.
Investigators work around the clock, but patrols operate on certain shifts.
Patrol Law-Shields eventually can be promoted to Investigators or Captains depending on what the District needs and the individual's aptitudes.
The base buildings are run by those who are learning how to become Patrol Law-Shields, and while many won't become Patrols, they are still a valued part of the guild, and can become the Record Keepers and Evidence Guardians.
