Two books, #30 The Shambhala Strike and #53 The Judas Scrolls mention Camellion studying at St. Louis University, where he received a Bachelor of Science degree.
Three other books (#1 The Death Merchant, #9 Laser Mission, #11 Manhattan Wipeout) mention that Camellion is an ex-teacher of history, but this may simply be a cover story.
Camellion donates an unspecified percentage of his fees for each mission to assist struggling college students and also the underprivileged in Texas (#17, "The Zemlya Expedition").
Examples: James Valdorian, Chester Giffwangle, Leonard Higgdon, Emil Milrich, Milton Sessions, Ludwig Huelsenbeck, Thomas Wang-Ji.
In later books, he never works for organized crime again but accepts missions from the ONI (Office of Naval Intelligence), NSA, CIA and MAD (West German counter-intelligence) The series is more nihilistic than many of its 1970s and 1980s action series counterparts; Camellion does not think twice about killing innocent people if it is the quickest way to get the mission accomplished.
For example, #62, The Soul Search Project sees his team killing 18 New York Police Department officers who try to stop them during a mission.
