Pilot Jack Cooper's History
Jack Cooper is the Pilot protagonist and the playable character of Titanfall 2's single-player campaign. Beginning his military career as a Rifleman in the Frontier Militia, he is the (eventual) Pilot of BT-7274 and ends up becoming a lynchpin of Operation Broadsword, specifically the hero of the Battle of Typhon, where Cooper uncovers and stops the IMC's plot to use a new-found super weapon to devastate the Militia.
Due to the radically skewed population and wealth distribution on Earth, Jack Cooper's family relocated to the Frontier in search of a better life when he was an infant. The rural Frontier community they inhabited was subjected to harassment and exploitation by IMC garrisons. As the IMC continued to disrupt the livelihoods of the people in his home system, Cooper volunteered as a Militia Rifleman to free the Frontier from the oppression of the IMC. One of his first assignments as a rifleman was during the battle of Fracture, where he suffered a head injury in the line of duty and had trouble remembering his involvement as a result.
Battle of Typhon
Tai Lastimosa, an SRS captain and Pilot in his own right, gave then-Rifleman Jack Cooper off-the-record Pilot training in virtual reality (VR) for an extended period of time before the game began. The first level of the game, The Pilot's Gauntlet, is one of these VR sessions. The training session is interrupted when the 9th Militia Fleet arrive at Typhon. Cooper and Lastimosa are deployed to the planet's surface.
During the first battle on the planet, Cooper's battalion is ambushed and surrounded by Spectre units. Apex Predator Titans show up to finish off the grunts, but Cooper is protected by Lastimosa and BT-7274. Lastimosa is mortally wounded in the process. Cooper awakens to find Lastimosa barely alive. With his last breath, Lastimosa transfers control of BT to Cooper. After giving Lastimosa a proper burial, Jack takes Lastimosa's jump kit and helmet and meets BT-7274, who recognizes Cooper as his new Pilot. Jack retrieves batteries for BT, and the duo escapes into the wilderness in an attempt to locate Major Anderson to complete Lastimosa's mission.
The two come across a water reclamation facility, where a battle is occurring between Militia and IMC forces. Cooper and BT fight through the facility and make their way to Kane, an Apex Predator responsible for the death of many Militia pilots in the battle. They kill Kane, and Cooper takes his helmet radio, allowing him to listen in on enemy communications.
Jack and BT press on, and they attempt to save time by taking a shortcut through what's revealed to be an IMC factory creating pre-furbished housing and simulated environments for testing purposes. The facility is controlled by Ash, the simulacrum Apex Predator. Cooper and BT are separated, and Ash torments Cooper throughout the facility with its deadly traps and trials for him and other captured Militia soldiers. After finding each other again, Jack and BT confront and destroy Ash before escaping the facility.
Afterwards, they arrive at Anderson's coordinates, which are at a classified, seemingly abandoned IMC research facility. Once Cooper ventures inside, he experiences strange temporal phenomena, which is later revealed to be a result of time anomalies in the area. They then locate Anderson's body, lodged in the ceiling. After Cooper retrieves Anderson's helmet, they uncover his mission: he was sent to the facility to locate and identify a new weapon being developed by the IMC. During the briefing hologram, they also discover that Anderson had been given a wrist mounted device which would allow safe passage through the facility. With Anderson's death, the command of Special Operation 217 transfers to Cooper. Cooper locates the other half of Anderson's body and takes the wrist mounted device, which is actually a time travel device that allows its user to travel forwards or backwards in time with a simple flick of the wrist. Cooper makes judicious use of the Time Gauntlet as he further infiltrates the complex, battling Prowlers and worn-down Stalkers in the present and assorted IMC grunts and Titans in the past. He eventually finds Anderson's objective: information on an IMC super weapon known as the 'Fold Weapon' and its power source, the 'Ark', which works by folding space and time to create untold levels of damage and destruction. Cooper discovers that the version being tested at the facility was a scaled-down prototype, and that the IMC - specifically General Marder and his ARES Division - have a full-scale version almost ready to go and aimed at Harmony, the Militia's "home" planet. BT and Cooper then leave the facility and search for a location to contact the main Militia fleet.
Jack and BT soon reach one of Typhon's Interstellar Beacons, an enormous satellite dish currently under the control of Militia survivors. After retrieving an Arc Tool and reactivating the reactor that powers the dish, Jack, with BT's throwing arm, repairs the dish. Before they can make contact, Richter, an Apex Predator, arrives. Jack and BT defeat the freelance pilot and reestablish contact with Commander Sarah Briggs and the Militia 9th Fleet. When Sarah arrives with reinforcements and meets Cooper and BT personally, she insists on finding a new Pilot for BT, as Cooper is still technically a Rifleman and thus not cleared to link with a Titan. BT protests on Cooper's behalf, citing their newfound chemistry and efficiency, and Sarah ultimately allows the duo to remain connected for the time being.
Cooper attaches to the 9th Fleet, as Sarah then initiates an all-out attack on the air base containing the Ark weapon. During the offensive, Sarah comes to acknowledge Cooper's skill as a would-be Pilot, effectively field-certifying him as a Pilot. Unfortunately, the attack ultimately fails when the Ark is loaded onto the IMS Draconis, a large transport vessel, which then flees the area and heads for the full-sized Fold Weapon. Jack, Sarah and the remaining ground forces are picked up by air transports and link up with the bulk of the Militia forces, taking immediate aerial pursuit of the Draconis and the Ark. With the aid of Barker and the 6-4, Jack takes control of the IMS Malta battlecruiser, which was hindering Militia pursuit of the Ark. Jack and BT then battle the Apex Predator Viper and kill him, and the duo successfully recover the Ark, but the Draconis crashes seconds later due to damage sustained.
Cooper and what remains of BT's chassis are captured by the last surviving Apex Predators, Kuben Blisk and Slone, who promptly interrogate Cooper on the whereabouts of the Ark. BT makes a last-ditch effort to save Cooper's life, but in so doing, the rest of his chassis is destroyed, and the Ark he was hiding in his cockpit is recovered by Blisk and Slone, who promptly retreat and leave Cooper to die. Cooper retrieves the Titan's core and the emergency SERE Kit within, which allows him to escape captivity.
Jack plants BT's data core in a new Vanguard chassis and tracks down the Ark on foot. After confronting and killing Slone at the Fold Weapon's central control station, Cooper and a heavily-damaged BT are confronted one last time by Blisk on-foot. However, out of a show of respect for the Militia Pilot's skill (or a willingness to stick to the letter of his contract), Blisk spares Cooper - to General Marder's extreme protest - and even extends a standing invitation to the Apex Predators before retreating. Cooper attempts to launch himself into the Fold Weapon and sacrifice himself to destroy it, but at the last second, BT extracts Cooper from the Titan's cockpit and hurls him away from the weapon's core, leaving only the Titan to sacrifice. Jack is then saved by Briggs and Barker, who make one last daring escape as the Fold Weapon is destroyed (resulting in the devastation of Typhon as a byproduct).
Cooper is hailed as a hero and officially sworn into the higher echelons of the SRS as a fully-certified Pilot, although he is reluctant to be assigned a new Titan, because nobody can ever replace his fallen friend. A message would later be sent through Cooper's helmet, with the binary code translating to the phrase "Jack?".
