Lieutenant Daniels was the tactical officer and the security chief aboard the USS Enterprise-E serving under the command of Captain Jean-Luc Picard from at least 2373 to 2375. (Star Trek: First Contact; Star Trek: Insurrection) Daniels was part of the defense of the Enterprise-E against the Borg, and took part in the failed attempt to reach main engineering and destroy the hive mind. Later he reported to Worf that the Borg controlled over half the ship, but had mysteriously stopped advancing.
