In the year 2025, US Special Forces operatives led by David Mason and his partner, Harper, arrive at "the Vault", a top-security location home to an elderly Frank Woods, whom they suspect possess vital information on the whereabouts of Raul Menendez. Woods concedes that Menendez has recently visited him, and shows them a locket that the latter had left behind. Frank then narrates several covert missions undertaken during his military career which span their previous encounters.
Three decades after the Invasion of Panama, Menendez re-emerges as the leader of Cordis Die, a massive populist movement with over a billion followers. He stages a cyberattack that cripples the Chinese Stock Exchange; in response, the Chinese ban the export of rare earth elements which the entire infrastructure of the US Army runs and relies on, fermenting the start of a new Cold War between the United States and NATO, against the Chinese-led SDC (Strategic Defense Coalition). Taking advantage of this stand-off, Menendez attempts to bring the two powers to a full-blown war by inciting conflicts between the two, secretly aiding SDC leader Chairman Tian Zhao. Using the intelligence provided by Woods, David, now a Navy SEAL code-named Section, leads JSOC forces in the renewed search for Menendez.
Shortly after gathering intelligence from Woods, Section and JSOC infiltrates Myanmar investigating a spike in activity in the region. There, Section's team encounters a computer engineer under Menendez's employment, warning them of a cyberattack with a Celerium device, a quantum computer capable of hacking any computer system. Section's team is later deployed in Pakistan, attempting to gather intelligence on Menendez's plots. During the infiltration, Menendez discloses the name of a target, "Karma" in the Cayman Islands. Section and SEAL operatives Harper and Salazar later infiltrate the Cayman Islands, finding out that "Karma" is a woman named Chloe Lynch, a former employee of Menendez's shell corporation, Tacitus. Lynch was the main developer of the Celerium device, and as a means of wrapping up loose ends, Menendez had deployed mercenaries for her abduction.
JSOC later has a lead on Menendez in Yemen, where JSOC asset Farid infiltrates Menendez's cell to help Section facilitate the leader's capture. The player, as Farid has a choice during the mission. Menendez, suspecting Farid's disloyalty, orders him to shoot the captured Harper. If the player chooses not to shoot Harper, and instead attempts to shoot Menendez, he fails, but Harper survives and is rescued. If the player chooses to shoot Harper, Farid survives, and Harper is not present in any conversations or missions thereafter. Menendez is successfully captured, but this was a ruse for Menendez to hack into the U.S. military's computer infrastructure on the aircraft carrier Barack Obama, seizing control of the United States' entire drone fleet. Salazar is revealed to be Menendez's mole within JSOC, and facilitates Menendez's attack—Menendez escapes with Salazar's aid, and when Menendez breaks in to the bridge of the Obama, Salazar shoots the soldiers guarding Admiral Briggs, with Lynch's survival dependent on Farid's survival in the previous mission.
The player, playing as Menendez, has the choice of either killing or wounding Admiral Briggs. If the player only wounds Briggs, and the player has completed all of the Strike Force missions, JSOC and SDC enter an alliance, then the player is later informed that the SDC sent hundreds of drones to defend the Obama, and consequently Briggs was able to save the ship and its crew. Menendez uses the drones to stage an attack on Los Angeles during a meeting of G20 leaders, hoping to kill them and cause catastrophic damage to the global economy. Section escorts the President of the United States to safety amidst the drone attacks.
JSOC eventually finds the source of the transmissions responsible for the hacking to Haiti, where Section leads JSOC forces into recapturing the facility in the final mission, and apprehending or killing Menendez. There are different endings depending on the actions the player takes throughout the campaign, such as whether or not the United States and China are able to enter an alliance with each other, as well as determining the fates of certain individuals in the game.
During the main campaign, the player may choose to participate in optional Strike Missions. The Strike Missions involve JSOC attempting to curb the SDC's global influence by preventing them from forcing neighboring countries into the alliance. Section himself does not participate in these missions directly, though he can command the forces remotely from a command center. If the missions are completed successfully, the SDC is weakened enough to ally with JSOC, forming an alliance between the United States and China, with the Chinese assisting the player later in the campaign, for example, in sending its own drones to rescue the U.S.S. Obama and sending its forces to assist JSOC in Haiti.
