|Political and military information|
During the Battle of Earth, his squad was dispatched from the UNSC In Amber Clad to relieve the ground forces. Their Pelican was shot down over Old Mombasa by a Scarab walker. He survived the crash, but his squad was soon attacked by a Covenant patrol. He was nearly killed by a Kig-yar Sniper but the sniper just missed him. A Sangheili then tried to sneak up on him with an Energy sword. Butkus' rifle was destroyed and he himself narrowly dodged the attack and fell to the ground, picking up a plasma pistol and charging it. As the Sangheili took Jones hostage, Butkus was able to shoot the Sangheili and save his squadmate. His squad then met up with the Master Chief and helped him to chase down and destroy the Scarab.
- Butkus is named after the Bungie employee John Butkus. He worked on the animations and cinematics for Halo 2.
- Butkus used a dropped Plasma Pistol to take down a Sangheili's shields, followed by a Battle Rifle burst from Stacker. This is commonly referred to as the Noob Combo.
