Operation Nightfall was a secret mission authorized by Senator David Palmer to assassinate Balkan war criminal Victor Drazen. A Delta Force team, led by Jack Bauer, was organized by Robert Ellis for the mission. Bauer was ordered to assemble a six-man operation detachment team that would infiltrate Kosovo by air, eliminate the threat posed by Victor Drazen, and move to a distant extraction point where they would be extracted by a Pave Hawk helicopter.
