The first season end credit black and white photos are by David Hume Kennerly, who won the Pulitzer Prize for Feature Photography during the Vietnam War.

Because of the difficulty in obtaining licensing for the continued use of copyrighted music, Tour of Duty lost the rights to many songs that were utilized from the show's original CBS run. Not only did this affect the show's opening titles, but many individual episodes had to be edited to remove these songs. Notable artists whose songs were removed include Jimi Hendrix, The Rolling Stones, Creedence Clearwater Revival, The Animals and Bobby Bare.
