A tech agent reported to Jack Bauer that Amador's laptop had extensive schematics for the Chandler Plaza Hotel, enabling CTU to determine the first target where the Cordilla virus was likely to be released.

Before she could access the evidence, three of Powell's accomplices (Forbes, Adam, and Jason) entered, killed the driver, the other agent, and Marianne, and captured Curtis. According to Forbes, the three bodies were placed in a van afterward.

Helicopter pilot
Flying Jack to retrieve the nuclear football
A CTU Los Angeles chopper pilot flew Jack Bauer and a second field agent into the Mojave Desert so they could retrieve the nuclear football from campers Jason and Kelly Girard. (The football fell down as debris from Air Force One, which had been damaged by Mitch Anderson in a stolen stealth bomber.) The pilot confirmed that the signal from the football briefcase was reading properly, and at 11:35, he dropped off Jack and the agent. Later, Jack called him to assist in bringing down an escaping Jeep driven by Steve Simmons, a terrorist who had the football. The pilot dropped low, shined his light in the driver's eyes, and caused the Jeep to crash. He then used the light to help Jack find the case, and flew away to track the other Jeep when ordered to. Shortly after midnight, when Jack was done working with Fred Laughton, the pilot returned Jack to the CTU Los Angeles building.
- The pilot was played by Michael P. Lugar in "Day 4 11:00pm-12:00am" and "12:00am-1:00am".

The worker pulled up the log, but it was quickly wiped for Audrey by Chloe O'Brian.
- The archives CTU worker was played by Tony Wayne in "Day 5 3:00pm-4:00pm".
- Tony Wayne also played Agent Powers during Day 2.
Stenger escort agent
As Jack and Curtis escorted Collette Stenger into CTU Los Angeles, one of the accompanying CTU agents informed Jack that Stenger had identified Audrey Raines in photographs on the ride over. This seemed to confirm Stenger's claim that Audrey sold her secret information. It enraged Jack, who threatened Stenger because he knew implicitly that Audrey was innocent.
- The escort agent was played by Tohoru Masamune in "Day 5 9:00pm-10:00pm".
Day 6
Agent at Wallace residence
Reporting that Scott Wallace is still a hostage
Jack Bauer and Curtis Manning led a CTU field team to the residence of Ray and Jillian Wallace to apprehend Ahmed Amar, a terrorist hiding there. This field agent reported to Jack that Scott Wallace was still being held hostage by Amar. As Jack, Curtis, and the rest of the team went in, Ahmed panicked, fired some shots blindly, and fled. Outside, Jack confronted Ahmed, but when Ahmed aimed his pistol at Jack, the field agent shot him down with his pistol. The wound left Ahmed barely alive. The agent stayed with Ahmed while a medic worked to revive him. At 9:48 he took a written statement from Scott Wallace. Five minutes later, Jack asked the agent where Manning was, but the agent didn't know: Curtis went to go threaten the life of Hamri Al-Assad.
- The field agent was played by Brian D. Johnson in "Day 6 9:00am-10:00am".
SWAT agent
A CTU Los Angeles SWAT team surrounded 4332 Florence Avenue in an effort to capture Abu Fayed, a terrorist ringleader with access to 4 stolen suitcase nukes at the time.

During the subsequent raid, Fayed escaped but one suitcase nuke was disarmed and all of the other sub-cell terrorists were killed.
- The SWAT agent was played by Brian Silverman in "Day 6 1:00pm-2:00pm".
SWAT medic
Tending to Mark Hauser
One of the CTU SWAT agents who went with Jack Bauer and Agent Ryan from 1530 Hillcrest to 8613 Bianca Drive to apprehend Mark Hauser was a medic. Hauser was shot during the raid on his house, and the medic determined that he had serious arterial bleeding. He tended to Hauser until the suspect made a call to draw Dmitri Gredenko out of hiding. Once the call was finished, the medic insisted that Hauser be sent to a hospital.
- The CTU SWAT medic was played by Eric Cazenave in "Day 6 8:00pm-9:00pm".
