I would suppose that there are many at very sensitive operations at headquarters and around the world that are moles or double agents a 5th column if you will that are in but mentally out and full of hated for the Governing Body.
A fifth column is any group of people who undermine a larger group from within, usually in favour of an enemy group or nation. The activities of a fifth column can be overt or clandestine. Forces gathered in secret can mobilize openly to assist an external attack. This term is also extended to organised actions by military personnel. Clandestine fifth column activities can involve acts of sabotage, disinformation, or espionage executed within defense lines by secret sympathizers with an external force.
