 The latter format is the more common style in CIA documents.Examples from publications by former CIA personnel show that the terms "code name" and "cryptonym" can refer to the names of operations as well as to individual persons.TRIGON, for example, was the code name for Aleksandr Ogorodnik, a member of the Ministry of Foreign Affairs in what was then the Soviet Union, whom the CIA developed as a spy; HERO was the code name for Col. Oleg Penkovsky, who supplied data on the nuclear readiness of the Soviet Union during the Cuban Missile Crisis of 1962.
