Colonel Day Kannu (2370)
Field Colonel Day Kannu was a member of the Bajoran Militia, and a secret member of the Alliance for Global Unity, also known simply as "The Circle".
In 2370, Day participated in the attempt to take over Deep Space 9 under the command of General Krim, with whom Day constantly argued as to what course of action to take in the mission. Although the space station at first appeared deserted, Day's infiltration team ultimately learned that a small team of Starfleet officers headed by station commander Benjamin Sisko remained behind to prevent the takeover.
While searching for Sisko, Day was lured into and trapped within a holosuite by the Starfleet commander. After fighting against several holographic opponents, Day was informed by Sisko that The Circle was receiving support from the Cardassians. Day refused to believe Sisko, however, and, after being released from the holosuite, continued the search for Sisko while neglecting to pass on Sisko's information to General Krim.
After finally learning the truth about the Cardassians giving aid to the Circle and that Day had failed to relay Sisko's message, General Krim opted to return command of the station to Starfleet. Angered by this turn of events, Day attempted to kill Sisko with a phaser, but accidentally killed Li Nalas, who threw himself into the blast to protect Sisko. (DS9: "The Siege")
