Butkis

Butkis was a UNSC Marine and Orbital Drop Shock Trooper stationed at Earth in 2552. He was part of the 7th Orbital Drop Shock Trooper Division.

During The First 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 Jackal Sniper but the sniper just missed him. An Elite then tried to sneak up on him with an Energy sword. Butkis narrowly dodged the attack and fell to the ground, picking up a plasma pistol and charging it. As the Elite took Jones hostage, Butkis was able to shoot the Elite and save his squadmate. His squad then met up with the Master Chief and helped him to chase down and destroy the Scarab.

He is presumed to be alive, since his CO Gunnery Sergeant Pete Stacker had returned to In Amber Clad afterwards, although he and other members of Stacker's squad weren't mentioned outside of Another Day at the Beach, so he may very well be a Flood Combat Form.
