This would basically function as a new inventory item for combative personnel, which can be used on Class-Ds and put on their arms. It’d help differentiate authorized CDs from non-authorized CDs, as well as add to immersion. They would be manually given to the CD after being briefed, and manually removed after being returned to Omicron.
An alternative to this is implementing something similar to the system for tagging CDs as DFSC, which would put a tag above the CD’s head reading “AUTHORIZED” or something similar.
