In Episode 104, the police officer who pulls Ali over on the mountain road responds to station radio communications with code "10-6," which means he is busy with a non-urgent matter. The station responds with police code "10-18" which is used to signal an urgent communication.
Trying to profile Jack Ryan's personality, Cathy Mueller isn't sure if he's a Type B or Type C. "Type A," is a term used to describe a highly motivated and potentially stress-prone personality type. The term was coined in the 1950's by cardiologist Meyer Friedman and his collaborator R.H. Rosenman. "Type B" tends to describe personalities that are laid-back and, therefore, the opposite of Type A. Type C describes individuals with repressed emotions.
When Al-Radwan meets with Suleiman, he makes a snide comment about a Yazidi servant. The Yazidi people are a population indigenous to northwest Iraq, northeast Syria and southeastern Turkey that has faced years of persecution and the threat of genocide at the hands of Al-Qaida and ISIS terrorist groups. Yazidis are a religious minority; the Yazidi faith does not accept converts, and 2014 estimates numbered the global Yazidi population at approximately 700,000.
Throughout Season 1, secondary characters and subplots are introduced that become meaningful in different ways as the Jack Ryan story progresses. According to executive producers, this narrative structure attempts to mimic Tom Clancy's signature mosaic storytelling style.
Most of the guns used in 'Tom Clancy's Jack Ryan' were real guns, loaded with blanks. The only time rubber weaponry was used was for the scenes in which Suleiman uses gun stock to strike Al-Radwan in the face.
