Early life
Arnett was born on March 23, 2011 in an unknown city in California. Once he turned 19, Arnett joined the Marines. He would later be assigned to SFR's Kilo Force One, lead by Sergeant Baker.

Kilo Force One
Arnett was one of two soldiers handpicked by Lieutenant Daniel McCoy to join Kilo Force One, along with Michael Hicks who joins the team later.

Camp Texas evacuation
He appears alongside Emerson as they escape Camp Texas. Arnett is ordered to follow Baker to the Hummers, while Emerson provides covering fire. The two later find a Humvee with Corporal Fletcher in the driver's seat. Baker orders Fletcher to get them out of the camp, to which he drives to the nearest exit. He is one of the few survivors of the attack, along with Baker, Emerson, Hicks, and Fletcher.

Infiltration
Lieutenant McCoy sends Baker and his team along with new recruit Hicks to infiltrate a warehouse occupied by a terrorist group. The team manage to recover some intel on the terrorists, but were ambushed by an overwhelming amount of enemies. They manage to eliminate all of the enemies and escape the warehouse in a stolen Technical, and report back to McCoy at the command post.

Rescue mission
McCoy tells Baker about the terrorists' leader, Tomáš Svoboda, and suggested the team to capture or kill him, since he has a large bounty on his head. But before they can do so, McCoy sends the team to Moscow, Russia, where they must rescue two American prisoners from a military prison, Sgt. McMillan and Pvt. Jackson. They enter the prison via a stolen UAZ-469, but a squad of Russian Army soldiers stops them before they can enter the prison, and tells the team that they are trespassing, and tells them to give them a valid reason why they are here, or they will execute them. Instead of bothering to answer the soldiers' questions, Baker and Hicks kill two of the soldiers, while Emerson and Arnett kill the other two. They steal the soldiers' uniforms and hide the bodies, and enter the prison. Baker then asks a guard to take his group to McMillan and Jackson's cells, but the guard questions Baker's authority. He then threatens the guard that he will tell the warden about the guard's actions. He begs Baker not to say anything, and Baker orders him to take them to the two Marines' cells.

The guard then questions why they wanted to see the two soldiers, to which Emerson tells him that they are bringing the soldiers in for interrogation. Confused, the guard decides to open their cells. While the guard was opening Jackson's cell, Emerson snaps the guard's neck, killing him instantly. Another guard sees this, and then tries to call in backup, but is killed by Hicks before he could do so. They then exited the cell block with Jackson and McMillian, Arnett then arms the two with AK-47s.

Little did the soldiers know, their actions were caught on security feeds, and the commander and warden of the prison would call in reinforcements in an attempt to kill the soldiers before they could escape the prison. When Baker and the team reached the exit, they were stopped by a group of Russian soldiers, and with Voloshin speaking over an intercom taunting the Americans, and orders them to surrender or they will be killed. Instead of doing so, Baker and Emerson engage the soldiers, and a firefight occurs between the Russian soldiers and Baker's team. However, they manage to kill off the remainder of the Russians and request exfil.
