Elias Walker

Captain Elias T. Walker is a main character of Infinity Ward's Call of Duty: Ghosts and a founding member of the defacto U.S. Elite Force, Ghosts, which was formed after an ODIN disaster that decimated the United States.

The ODIN disaster of 2016
After telling the story of Ghosts' origin to his sons: David and Logan, tremors started happening. At first, Elias and the Walker brothers believe it to be a typical San Andreas fault movement, that is until Elias started noticing massive explosions coming from under the Earth's surface causing masive craters. Elias relized that it was ODIN turning against them(thanks to the Federation), and is firing tungsten missiles from orbit at all of the U.S. land. After telling his sons to get back home, Elias went to check on what's going on. After a tanker truck exploded, he and David carry an injured Logan to safety.

2026: War Against the Federation of the Americas
Elias was the commanding officer of the Ghosts forces, which included his sons, David and Logan, and old friends Thomas Merrick, Keegan P. Russ, and Alex "Ajax" Johnson. He overlooked many of Ghosts' ops in 2028, including the op of "No Man's Land", the rescue attempt of Ajax, the defense of Fort Sanata Monica, "Federation Day", and the capture of former Ghost: Gabriel Rorke.

Death
While on a mission in Las Vegas, Elias and his sons were captured by Rorke after the latter escapes from captivity of his prior squad. When told to undermine Keegan's arival, Elias refuses and is roughed up by Rorke. While Logan was trying to kill Rorke, Elias was accidently shot by his youngest son and Logan was thrown to the floor. Before being shot and killed, Elias reassured Logan and implies that he's proud of his sons.
