OGA
From Wikipedia, the free encyclopedia
OGA means 'Other Government Agency'. It is a sly way of referring to the American CIA or its counterparts in other countries.
A CIA operative may have a need to discreetly reveal his or her origins; for example, if a CIA agent is embedded in a friendly military expeditionary unit, the agent will need the co-operation of the unit in order to successfully conduct operations. On the other hand, the agent must maintain as much secrecy as possible and cannot brag about his or her origins. The agent might therefore refer to him or herself as 'OGA'.
The term is frequently referenced in popular espionage fiction such as the works of Tom Clancy.
