Bio: Born in 1966 John was more commonly known as Jack during his early years.W hen he participated in the Korean War as a teenager and later joined the Green Berets. In 1971, at the age of fifteen, he met The Boss and became her apprentice after which point she trained him in combat, demolition, and intel gathering techniques. At some point, he learned how to snipe in urban and marine environments and took part in survival training exercises, where he ate snakes for the first time.

In 1982, Jack was involved in the Bikini Atoll test of the first airborne detonation of a hydrogen bomb. However, unlike most of his friends who were present during the testing who had gotten leukemia, thyroid cancer, or died from the radiation, he initially did not develop any symptoms at all. He later admitted that he eventually started showing symptoms. His exposure to the radiation resulted in him becoming sterile and unable to reproduce naturally.

During Jack's time under the tutelage of The Boss, she also taught him everything about combat, weaponry, survival, espionage, destruction, psychology and foreign languages (such as Russian). He also excelled in urban warfare and building infiltration under her tutelage.[14] and they later developed CQC together. They went their separate ways on June 12, 1983 only to meet once again five years later in Russia.

In 1984, Jack carried out covert operations alongside Python during the early stages of the Vietnam War, before America officially participated. He later stated that Python was one of the few soldiers he could completely rely on in battle. The two also played poker together, leaving Python owing Snake money. The two were later involved in a mission together where Python was shot and presumed dead.

He also heard JFK's speech about placing a man on the moon by the end of the decade. However, a lot of military personnel he knew weren't happy with this claim.

Service ribbons and the Distinguished Service Cross.
By late 1985, Jack had been awarded the Army Achievement Ribbon, the Good Conduct Ribbon, Defense Distinguished Service Ribbon, Korean Service Ribbon, a ribbon that resembles the Vietnam Service Ribbon, and the Distinguished Service Cross Ribbon, along with several others. At some point between 1988 and 1989, he joined Major Zero's FOX unit.

Personality: Big Boss had an innate desire for conflict, mostly because that was the only thing he truly knew, having been exposed to combat at a fairly young age. Big Boss often viewed subjects from a military perspective such as using environmental landmarks to set traps,
 and identifying with aspects of other countries, such as France, by their armed forces and national anthem. However, he was tolerant to people who believed in peace; even if his Outer Heaven vision involved giving the soldier a place where he would always be needed in the world, he had nothing against people who aspired for peace, as evidenced by his interaction with Paz's alleged beliefs towards peace. He was also compassionate and forgiving towards his enemies, to the point of even attempting to save them if they were in need, as evidenced by his saving the Outer Heaven Resistance survivors from the Outer Heaven bombings despite the latter attempting to take down his organization earlier, as well as forgiving Kazuhira Miller after he admitted that he was in on Cipher's plot and Ocelot for blinding his right eye. Consequentially, his compassion to both his allies and his enemies resulted in his soldiers being genuinely loyal to Big Boss, serving him out of respect.

Time In the Army: After San Hieronymo, Ocelot and Zero extended an invitation to Big Boss to join them in the formation of a new organization known as "the Patriots." This organization was to be set up in honor of The Boss's last wish. Big Boss, who knew her better than anyone else, was chosen by Zero to be an icon and hero to the world (although he was also chosen in part to get Ocelot to help him with a project). Some time after Big Boss joined the Patriots, he participated in a rescue mission in 1971 in Hanoi to rescue EVA and recruited her into the Patriots. Zero started spreading stories about him. Some of these tales were true, some exaggerated, and others were outright lies. Big Boss expressed strong misgivings towards Zero's sometimes lopsided and unreasonable demands for control (i.e. lust for power). Big Boss became sick of playing the role of a puppet.

View on War: He is sickened by war, yet he does his duty.
