Tanner was complicit with the Jacobs administration for rushing the development of a hybrid fighter that killed Steven Hiller in the 2007 ESD Spring Expo. Prior to the incident, ESD scientist David Levinson warned Tanner about his concerns about the hybrid in which Tanner disregarded his warnings and had him removed from the hybrid project. Much to Tanner's reluctance, Levinson was appointed as the new ESD Director.
War of 2016
During the upcoming 20th anniversary of the War of 1996, an unknown alien spaceship appeared on the Moon. Tanner was very vocal to implore President Lanford to deem the ship as a threat. Lanford eventually conceded to giving permission to the ESD to destroy the vessel.
Tanner participated in the anniversary in Washington, D.C. and was witnessed to the arrival of the Harvester mothership. He and along with Lanford's Cabinet evacuated to Cheyenne before the mothership devastated the American east coast. After a failed counterattack against the Harvester, the aliens assaulted Cheyenne and Tanner was killed.
