- The following is based on the account of Operation Nightfall from Findings at CTU, which was later retconned in 24: Nightfall.
Bauer chose Illijec as the communications officer for Operation Nightfall, a mission to assassinate Yugoslavian military leader Victor Drazen at his compound in Đakovica. The team also included second-in-command Dwayne Shelton, weapons officer Brice Gardener, medic Gary Graham, combat controller Roger Voss, and intelligence specialist Fred Peltzer. After reactivation and briefing at Fort Bragg, the team flew to Aviano Air Base to deploy to Kosovo aboard an MC-130 Combat Talon.
After infiltration, Anvil Team followed the Erenik River until they reached the road to the manor compound where Drazen was supposedly hiding out. While Shelton, Gardener, and Graham broke off to disable the facility's antiaircraft guns, Illijec, Bauer, and Peltz went on a reconnaissance run of the house and barn. After Hammer One destroyed the compound, however, the team's radio frequency was jammed, resisting Illijec's efforts to reestablish contact. Bauer ordered Illijec and Peltz to head to the evacuation point while he went to assist the second team, but the two men were ambushed at the riverbank by Drazen's forces and killed in the firefight.
