 * U.S. Covert Operations Manual - Whistling in the Dark might be a reference to the Splinter Cell series where the player can whistle to lead enemy guards to their location.
 * U.S. Covert Operations Manual - Not the Soldiers You're Looking For is a reference to Star Wars: Episode IV: A New Hope, where Obi-Wan Kenobi says "These aren't the droids you're looking for".
