"A Marine’s Marine who truly believes in the rule of law, few NCOs in the Corps are more beloved than Marcus Griggs. Fair, capable, and charismatic, Griggs can motivate and inspire troops in ways other officers only dream of."
Griggs' voice is heard near the end of the Season Six cutscene as he awaits John Price's order. He was released on November 10, 2020 during the Season Six of content for Modern Warfare as part of the "Sgt. Griggs Operator Bundle".
In the cutscene for the intel mission "The War Room", Griggs is heard saying that him and his unit, the Demon Dogs, have cordoned off the silo. However, they are not seen.
