A Handler (ハンドラー, Handorа̄?) is a position within the Republic Armed Forces tasked to oversee the Republic's drone squadrons and provide tactical support during combat. They are stationed within the former royal court of Palace Blancneige. To communicate with the Processors, Handlers use the Para-RAID device to synchronize with the hearing functions of the Processors.
The position of Handler is presumed to have been in use since the development of the M1A4 Juggernaut and the Para-RAID. However, due to the widespread discrimination against the Eighty-Six and the use of military positions as temporary jobs for the unemployed of the Eighty-Five Sectors, many Handlers are ineffective commanders. Some go as far as to deliberately mismanage their squadrons, often leading to unnecessary casualties. Capable commanders such as Major Vladilena Milizé are few within the ranks of the Handlers.
