Ghosts (Call of Duty)

The  Ghosts, officially known as  Task Force: STALKER, are a friendly faction that appear in Call of Duty: Ghosts  They are composed of the remnants of the U.S. Special Operations Forces. They are also playable in multiplayer, where they fight against the Federation .

The Ghosts were formed at some point prior to the Federation War. The group has its roots in Operation Sand Viper, a legendary battle fought presumably during the Tel Aviv War in which, sixty American soldiers from various Tier One Special Forces teams were deployed to fight off an enemy force of five hundred soldiers from overrunning a civilian hospital. Even though they were heavily outnumbered, the American soldiers decided to stay and defend the hospital with their lives, aware that the enemy would massacre its occupants.

Over the course of three days, their numbers were reduced to fifteen soldiers. Knowing that they could not last another night of fighting, the hospital was evacuated overnight and the evacuees led to safety by one of their men. The remaining fourteen soldiers hid amongst the bodies of their fallen comrades across the battlefield and waited for the enemy's attack. Blood from the bodies dripped over them and sand adhered to their faces, providing impromptu camouflage. When the enemy soldiers finally advanced, the soldiers rose from the bodies and ambushed them. The battle was long and fierce; the Americans fired their guns until they ran out of bullets, then used their combat knives until the blades were dulled, then at last resorted to fighting with their bare hands.

In the end, the soldiers slayed all of the enemy except for one man, who was later found traumatized and wandering in the desert. He reported that his unit was wiped out by "a force so menacing and unbeatable, it can only be described as supernatural," and called them "Ghosts."

The legendary American soldiers who fought in that battle became the first Ghosts when the group was formally established; among them were Elias T. "Scarecrow" Walker, Thomas A. Merrick, Gabriel T. Rorke, Keegan P. Russ, and Alex V. "Ajax" Jhonson.

And after the Federation War and the atack to Los Angeles city, the sons of Elias Walker,  David "Hesh" Walker and Logan Walker, joins to the Ghosts.
