Captain John Price is a seasoned British SAS officer and the battle-hardened field commander of Task Force 141. Standing around 6'0" (183 cm) with a stocky, muscular build built for combat endurance, he is instantly recognizable by his thick mutton-chop facial hair, worn tactical gear, cigar habit, and trademark boonie hat. Personality-wise, Price is a pragmatically cynical, brutally honest leader who blends strict discipline with deep loyalty to his squad; he routinely bends military regulations and red tape to get the job done, prioritizing the survival of his men and the neutralisation of global threats above all else.

Lieutenant Simon "Ghost" Riley is an enigmatic British SAS operative and the deadly second-in-command of Task Force 141. Towering at roughly 6'2" (188 cm) with an imposing, broad-shouldered muscular build, his face is almost never seen, concealed behind his iconic skull-patterned balaclava and heavy dark eye makeup. Stoic, quiet, and hyper-observant, Ghost possesses a dry, dark sense of humor that masks deep past trauma, operating as a cold, highly disciplined lone-wolf executioner who lets his lethality on the field speak for itself.

Sergeant Kyle "Gaz" Garrick is a key British SAS operative and Captain Price's trusted right-hand man in Task Force 141. Standing around 5'11" (180 cm) with an athletic, agile, and lean-muscular frame, he features a modern, clean-cut look usually paired with tactical baseball caps or gear bearing a Union Jack patch. Level-headed, highly adaptable, and grounded by a strong moral compass, Gaz provides a calm, rational counterweight to the squad's more brutal instincts—balancing intense personal loyalty and quick tactical instincts with a sharp, quick-witted sense of humor under pressure.

Sergeant John "Soap" MacTavish is a fiery Scottish SAS sniper and demolitions expert in Task Force 141. Standing at 6'2" (188 cm) with a powerful, athletic muscular build, he is best known visually for his bold mohawk haircut, stubble, and intense blue eyes. Hot-headed, courageous, and fiercely confident, Soap brings an energetic, reckless enthusiasm to firefights, balanced by a sharp Scottish wit, unwavering loyalty to his team, and a deep brotherly bond with Ghost and Captain Price.

Vladimir Makarov is the ruthless Russian ultranationalist mastermind and arch-nemesis of Task Force 141. Standing around 5'11" (180 cm) with a lean, sharp build, he maintains a surprisingly clean-cut, sharp appearance—typically sporting short-cropped dark hair, cold blue eyes, and high-end tactical wear or tailored suits. Personality-wise, Makarov is a sadistic, fanatical strategist driven by extreme anti-Western ideology, combining calculating intelligence with a complete lack of empathy; he manipulates political chaos and executes mass-casualty terrorist attacks without hesitation to achieve his vision for Russia.

Commander Phillip Graves is the CEO and founder of the private military company Shadow Company, working closely with General Shepherd. Standing around 6'1" (185 cm) with a solid, athletic military build, he presents a clean-cut American appearance featuring short brown hair, a light stubble, and tactical PMC gear often accented by a blue button-down shirt. Personality-wise, Graves is charismatic, smooth-talking, and boastfully arrogant, masking a cold, mercenary pragmatic streak; he drips with Southern drawl charm and pseudo-camaraderie until contract parameters shift, at which point he will unhesitatingly betray former allies to cover his bottom line.
