Grinch

Sergeant First Class "Grinch" was the callsign of an operator who served in the U.S. Army's "Delta Force", in Call of Duty: Modern Warfare 3. He was a Sergeant First Class who served in fireteam Metal (as Metal 0-3) alongside operators Frost and Truck under the command of Sandman. He served as the designated marksman for the team. Little is known about his past, but he possesses a southern accent, indicating that he probably grew up or spent considerable time in the southern United States.

Delta Force Sergeant First Class
Grinch fought in the Battle of New York along with the rest of Team Metal. He participated in combat actions aimed at destroying the radio jamming device that was allowing the Russians to gain superiority in the battle before being extracted from the roof of the New York Stock Exchange via Black Hawk helicopter. He and the team were then inserted into New York harbor, where they rendezvoused with U.S. Navy SEALs and boarded a Russian submarine, launching its cruise missiles at the Russian fleet.

Two months after the Battle of New York, Team Metal was redeployed to Hamburg, Germany, in the aftermath of a series of chemical attacks across Europe. Along with Truck, Grinch stay behind while Team Metal fought their way to the U.S. Vice President and freed him from Russian forces who had captured him, and extracted him from the city. Soon after this, the unit was ordered to capture a French bomb maker named Volk, who facilitated the chemical attacks across Europe. They successfully apprehended Volk with the aid of the French GIGN. Intelligence that Volk gave up led Delta to Berlin, where they attempted to rescue the Russian President's daughter, Alena Vorshevsky from Makarov's men. Two other Delta teams, Onyx and Granite, were killed in action during this operation, and Team Metal arrived too late to rescue Alena.

Ultimately, Delta joined with the disavowed John Price and Yuri in a mission to rescue Alena. They arrived at Makarov's stronghold in a diamond mine in Siberia, where Delta, Price, Yuri, and other U.S. Army assets assaulted the mine. They successfully rescued Alena and Russian President Boris Vorshevsky. However, during extract, Grinch, Truck, and Sandman fell behind to cover Price and Yuri as they escaped with President Vorshevsky. Sandman ordered the helicopter to extract without Metal, who were surrounded on three sides and running low on ammunition. As the helicopter escaped, the mine collapsed, burying the Utranationalist Russians as well as most of Team Metal.
