Agent Gordon during a cutscene
Agent G. 
Operation Swordbreaker (Cutscene)
The Great Destroyer (Beginning Cutscene)
At the moment of Cole's death in the mission Kaffarov, Henry Blackburn was put to detention, and two CIA officers came to interrogate him, one is Agent Gordon. Gordon is the focused interrogator to ask Blackburn about the events of the war; his missions, assault on Al-Bashir, and on finding the three nuclear weapons.
His personality is sort of a good cop unlike Agent Whistler. He normally is calm with Blackburn and never argues with him. He intentionally listens to the soldier's explanations, and speaks in a soft, calm voice. He also reassures Blackburn from time to time during the interrogation that if he cooperates he may "Get out of the world of crap you currently inhabit."
- His appearance is taken from Glenn Morshower, who also voices him, Glenn Morshower is also the one who voiced the character Overlord from Call of Duty: Modern Warfare 2. Moreshower is well known for playing Aaron Pierce, a Secret Service Agent assigned to the President's security detail in Fox's 24. Morshower was also seen as General Morshower, the commander of an F.O.B. in Qatar in the 2007 feature film Transformers, he reprised his role in the films two sequels.
- His name and Whistler's are only mentioned as a tip in the loading screen for The Great Destroyer. In the credits, he is only referred to as "Agent G."
