He was known for wearing the ketracel-white tubes of Jem'Hadar he killed as a necklace. He also possessed a Jem'Hadar knife, which he presumably took from a dead Jem'Hadar. Reese survived the final Jem'Hadar attack and left the planet on the USS Defiant. (DS9: "The Siege of AR-558")
Reese was played by Patrick Kilpatrick.
In the Tales of the Dominion War story "Requital", Reese, with help from Ekoor, tried to assassinate the Female Changeling during the events of "What You Leave Behind". Benjamin Sisko talked Reese out of doing it and sent him into counseling.
