First Lieutenant Kirk Graham, aka Wizard, is an intelligence officer with the Ghosts.
Wizard is described as having worked with Scott Mitchell so long that the two seemingly know each other's thoughts. Wizard briefs Nomad's team alongside Mitchell for their mission in Venezuela.
Following a bar brawl, he recommended Holt for admission into the elite unit.
In 2024, he directly supports Scott Mitchell around the time of the Raven's Rock coup.
He is considered by fellow soldiers to be "nerdy".
