Bauer and his team moved into position around a house containing the target, Victor Drazen, a known war criminal in Slobodan Milošević's "ethnic cleansing" machine. The house was laser-designated, and it was originally thought that Stephen Saunders had gotten too close to the blast and had died as a result, though it was later realised this was not the case (see below). As the rest of the Delta team attempted to withdraw to the extraction zone, they were ambushed by Serbian forces. Radio communication had been jammed. Every member of the Delta Force detachment, with the exception of Captain Bauer, perished in the operation.

During the events depicted in Day 1, Jack, who had since left the military and joined the Los Angeles branch of the Counter Terrorist Unit, realized Victor was alive. When he was captured by Drazen, Jack learned that the building had been occupied by a body double, and that Drazen's real wife and daughter had been inside the building. Bauer then realized that all the attacks of that day amounted to a personal vendetta designed by Victor's sons Andre and Alexis, against Jack and Palmer for the events of Operation Nightfall. The revenge was intended to be "an eye for an eye." This page refers to a fictional organization Counter Terrorist Unit. ...

It was also later revealed in Day 3 that Stephen Saunders had actually survived the blast and had been kept captive and tortured by Serbian forces for two years. During this time Saunders underwent a profound change of character. When he finally escaped, he had a vendetta against the United States' foreign policy and blamed the country, as well as Jack Bauer, for what happened to him. This eventually culminated with his acquisition of a new strain of a very deadly virus and attempt to release it which is the main terrorist plot theme throughout Day 3.
