In this comic books series, Marcus Fenix is training a new recruit, Jayson "Jace" Stratton. Delta Squad, composed of Marcus, Dom, Jace and Gil, is searching the Badlands for lost squads. They find another Gear, Corporal Michael Barrick of Echo Six. The rest of the members in the squad had been KIA. They set up camp and Dom and Marcus tell war stories to the other squad members. In the morning they encounter some locust drones. Gil gets seriously wounded just before two boomers arrive. While the rest of the squad takes out the enemy, Gil dies in Jace's arms. Jace recalls his own brother dying in his arms, but unlike then, Jace cannot shed a tear. The squad returns to Jacinto for a week's break. Dom and Anya meet, and Dom tells her that he appreciates the fact that she looked for his wife Maria. Anya then proceeds to meet Marcus Fenix in a bar. Two tough guys try to pick up Anya in a rough manner but Marcus hurts them to get them off. Once they find out who Marcus is, they lay off for good. The week is up and Dom, Marcus and Jace head out to find out that Michael Barrick is now in their squad.
During the invasion of his home Island, Tai Kaliso fought Indie soldiers in the jungle. After witnessing his village being cleansed by the UIR, Tai recognizes he has nothing to live for and ran into a member of the 26th Royal Tyran infantry. That same Gear, Marcus Fenix, invited Tai to fight for the COG, since he wanted him to be on the winning side. Years later Tai, along with the 26th, was fighting in Aspho Fields. Tai easily killed an Indie and mortally wounded another, giving comfort to the dying soldier but using his body as a Meat Shield after his death. Many years later, after the Lightmass Offensive, Tai explains to Jace that life is sacred. Later, during the Assault on Landown, Rig D77 is destroyed by Tickers but Tai was able to survive. He then joined up with Delta-One. Hours later Tai and Dizzy engaged Skorge in a melee combat. Realizing Skorge could not be beaten, he ordered Dizzy to escape. Tai was captured by the Locust, and "processed". After hours of torture, Tai's soul was ready to leave his body, and when Delta rescued him Tai took his own life.
In the comic, Jonathan Harper tells his own story. His story begins as his squad cheers on as the train carrying the Lightmass Bomb took off. Later he tells how he and his squad witnessed the bombing and thought it was beautiful. When he states the Locust weren't completely wiped out, he stated a new threat emerged, Rust Lung. He said several soldiers were tested for a new disease, Michael Barrick called it Rust Lung. Vivian Merriweather told Jon he didn't have Rust Lung, but he was unable to handle fighting which Jon took offense of. He was later given medicine. He was sent down into the hollows for Operation Hollow Storm. He was later captured and got very ill. He escaped the prison he was captured in, the same one as Maria's, and rescued a family evacuating out of Jacinto by taking some bullets where he perished near the sinkhole.
