According to Patricia Riggen, director of episodes 103, 105 and 107, working with military advisers on Jack Ryan was "fascinating." The raid from Episode 107 is an example of a scene that contrasts the expected narrative of a 'guns blazing' hostage extraction and targeted killing operation, but, according to Riggen, Delta's slow and noiseless assault is much more realistic than other fictional military raids audiences may have seen.
Episode 107 of 'Tom Clancy's Jack Ryan' features a reference to the CIA's Memorial Wall. The wall features permanent engravings of five-point stars to represent CIA officers who have died during service. The fallen are also memorialized in the CIA's Book of Honor, which sits in a display case below the Memorial Wall. The book lists the names of the deceased whenever possible, though some of the dead remain publicly anonymous.
