BattleField 3

Set in 2014, Sgt. Blackburn leads a five-man squad on a mission to find and safely return a US squad investigating a possible IED in Sulaymaniyah, Iraq, whose last known position was a market controlled by a hostile militia called the PLR. Several weeks later, the US sends Marines into Iran. Naval aviator and F-18 pilot Lt. Hawkins engages fighters over Iran and takes part in an air strike against Mehrabad Airport. In the aftermath of the air strikes, Blackburn and his squad are sent to Tehran to perform battle damage assessment and apprehend the leader of the PLR, Al-Bashir. While investigating an underground vault in the target's suspected location, Blackburn and his team learn that the PLR acquired Russian portable nuclear devices, and that two of the three devices are missing. Being overrun, and requesting back-up, an M1 Abrams convoy led by Sergeant Miller is deployed to extract Blackburn's team. Miller facilitates Blackburn's helicopter extraction, but is captured when waiting for a Quick Reaction Force. Miller is promptly executed by Solomon and Al-Bashir, with the event being filmed.
Later, Blackburn and his squad manage to capture Al-Bashir, who realizes Solomon betrayed him and reveals his plot to detonate the nukes in Paris and New York, before dying from the wounds he sustained in his capture. Blackburn's team also gets a lead on an arms dealer, Kaffarov, who was working with Solomon; however, while pursuing Kaffarov, the Americans encounter a large Russian force, who are also attempting to apprehend Kaffarov and are hostile towards the Americans. Almost all of Blackburn's squad is killed, while a Spetsnaz team led by Dima assaults Kaffarov's villa. Dima successfully interrogates Kaffarov, and reveals Solomon's plot to Blackburn.
Blackburn's commanding officer arrives and to save Dima's life and let him escape, Blackburn shoots the commanding officer. Due to this, Blackburn is captured and interrogated by agents within the Central Intelligence Agency (CIA) and explains all of his previous operations to them in flashbacks. During Blackburn's capture, Dima attempts to stop the attack in Paris, but he is unsuccessful and his team is wounded in the resulting detonation. The CIA agents do not believe Blackburn's story, since Solomon is a CIA informant and there is no concrete proof of his involvement in the terrorist attacks. They instead believe that Russia is responsible for the attacks and that Dima had played Blackburn.
Left with no other option, Blackburn and surviving squad member Montes break out of captivity to stop the attack in New York. As a result of the chase after Solomon, Montes is killed but Blackburn manages to kill Solomon by hitting his head repeatedly with a brick as well as recovering the last nuclear device. In the epilogue, having been diagnosed with radiation poisoning, Dima writes about the efforts of both him and Blackburn to stop Solomon's plot. He then readies his gun when a knock is heard at his door.
