When you create your character, you must pick a single Authorisation from the list of Unrestricted Authorisations. This Authorisation represents what your Character has access to in the field.
Restricted Authorisations cannot be picked at Character Creation and must be granted during play.
Your Character's Authorisation will be displayed on their ID Badge.
You can change your Character's Authorisation between events or during an event by agreement with your Line Manager, and Characters can also temporarily be granted (or revoked) Authorisations, including Restricted Authorisations, in play.
These must be granted in play and will only be granted for a limited period of time unless explicitly stated otherwise. Not all Restricted Authorisations are common knowledge, but here listed are the most commonly known ones.
