Field Unit Bravo was a CTU Los Angeles TAC team active during Day 6.
Day 6[]
The team and its leader, Mike Doyle, was directed by Nadia Yassir to capture the Chinese operative Cheng Zhi at the Bloomfield facility in Jefferson Heights and retrieve an extremely important subcircuit board from him. Cheng and his men had moved, however, and Field Unit Bravo was too far away to help during the invasion of the CTU Los Angeles building by Cheng's mercenaries.
The team returned to CTU and met up with Jack Bauer. The team, with Bauer and Doyle, pursued the mercenaries with their hostage, Josh Bauer. They infiltrated an underground parking garage, where Cheng was holding Josh. Jack killed the driver of Cheng's limousine as he drove, and a large gunfight ensued. Cheng used Josh as a human shield to protect himself from gunfire. In order not to shoot Josh, Jack ordered Field Unit Bravo to stand down. Josh was saved, but in the process, Cheng escaped.
