In the film series, Jason Bourne is revealed to have been born as David Webb on September 13, 1970 (or June 4, 1978 in "Jason Bourne") in Nixa, Missouri (although in "Ultimatum", he is given a false date of April 15, 1971, as a coded reference to a specific site). In flashbacks, he joins the United States Army and is eventually selected for Delta Force in 1998. His father, Richard Webb, a senior CIA analyst, is responsible for creating the Treadstone program, a black ops project intended to train and deploy elite assassins. The CIA murders his father with a car bomb in Beirut in a bid to recruit Webb.
