Jack Mitchell

"In Call of Duty: Advanced Warfare, you assume the role of Private Jack Mitchell, a young Marine who finds himself reborn as a soldier working for the ATLAS Corporation."

- Jack Mitchell description on the official Call of Duty website

Private Jack Mitchell is the main protagonist in Call of Duty: Advanced Warfare. He served in the United States Marine Corps before his best friend, Will Irons was KIA. After Will's death, his father Jonathan Irons offered Mitchell a job at the Atlas Corporation.

Sledgehammer Games studio head Glen Schofield has stated that Mitchell will speak only during cinematic sequences, otherwise remaining silent so that gameplay isn't interrupted by the player character's speech.

Early life
Mitchell's father was a Marine, which eventually led to his son being made to join the Marines. Mitchell enlisted together with Will Irons, who he considers his best friend.

United States Marine Corps Service and South Korea
Six months after enlisting in the Marines, Mitchell, Irons and many other soldiers were called in to drive away North Korean forces from Seoul. While attempting to set demolition charges to an enemy transport ship, Irons' arm got stuck in a panel. Both Mitchell and Irons attempted to escape, but Irons then pushed Mitchell off the ship and sacrificed himself. Mitchell himself, however, was severely wounded as a piece of the ship flew at him and ripped his left arm out.

Second Chance and Atlas Training
After losing his arm back in Seoul, Mitchell was discharged from the Marines. While attending Will's funeral, Will's father, Jonathan Irons admired Mitchell as a good soldier and told him he could join his private company, Atlas, for a "second chance". After getting a card from Irons, Mitchell soon joined Atlas and participated in a simulation with a new prosthetic arm gifted by Irons himself. Under the command of Joker, the team raided a house in Maryland in order to rescue the President of the United States. After rescuing him and avoiding detection from a drone patrol, they proceeded to the patio area, where after reloading, his left arm started to malfunction, but Mitchell shrugged it off. However, after attempting to open a car door with his left arm, it utterly failed, giving Gideon a chance to attack Mitchell, "kill" the President, and point his gun at Mitchell's face. However, Gideon then ordered a restart to the simulation, where Irons then arrives. Irons and Gideon then gave Mitchell a tour of the ATLAS HQ and Irons then dropped Gideon and Mitchell off to get Mitchell's arm fixed. After getting it fixed, Mitchell does some shooting and grenade testing before redoing the simulation with Gideon and Joker again, this time successfully, where Irons then fully welcomes Mitchell to the Atlas Corporation.
