"He was a member of the Special Tactics And Rescue Service and served as Alpha Team's point man. As a former member of the United States Air Force, he is also an experienced fighter pilot. He is the older brother of Claire Redfield and a current member of the BSAA where he, Jill and nine others co-founded the organization. In Resident Evil 6, he serves as an Special Operations Unit captain of the BSAA. He was voiced by Scott McCulloch in the first Resident Evil followed by Michael Filpowich in Resident Evil Code: Veronica and Joe Whyte in the Nintendo GameCube remake of the original title. Roger Craig Smith voices Chris in Resident Evil 5 until Revelations 2 where he is a playable character in Raid Mode. In the movie, Resident Evil: Vendetta and the upcoming movie Resident Evil: Death Island, he is voiced by Kevin Dorman who previously voiced him in Umbrella Chronicles and for motion capturing Leon S. Kennedy in the movie Resident Evil: Damnation and Piers Nivans in Resident Evil 6. In Resident Evil 7: Biohazard, he is voiced by David Vaughn. Jeff Schine, the voice actor of Carlos Oliveira in the remake version of Resident Evil 3, voices Chris in Resident Evil: Village.
Chris is close to his friends and family, specifically with his younger sister Claire and his partner Jill Valentine, whom he would both willingly give his life to protect.He also establishes bonds with the people he works with, respects (Rebecca Chambers and Albert Wesker for example) or admires.He cares deeply for the life of innocents, something which caused him to argue with his superiors in the military. Chris has a long-standing friendship with Barry Burton, who was an old friend of Chris' family. Barry was the one who recruited Chris for the Special Tactics And Rescue Service after Chris had left the Air Force and began drifting.

Serving as Point Man in S.T.A.R.S. Alpha Team, Chris earned the trust of his comrades. In particular, Chris developed a close friendship with Jill Valentine, the only female member of S.T.A.R.S. at the time.

Forest Speyer, the sharpshooter of the S.T.A.R.S Bravo Team, was once a great friend (and rival) of Chris, until the Mansion Incident in 1998, where Forest was brutally killed and turned into a zombie.

After the Mansion Incident, Chris became obsessed with the Umbrella Corporation, seeking information to bring the company down and avenge the deaths of his friends. Later, Chris and Jill formed a lethal organization to combat Umbrella together, the Bioterrorism Security Assessment Alliance, aka, the BSAA.

Formerly, during his activity in S.T.A.R.S., Chris exhibited great respect for the S.T.A.R.S Alpha Team leader, Albert Wesker, who recognised Chris as his most skilled team member. However, since Chris ruined, or at least delayed Wesker's plans at the Spencer mansion, a powerful grudge formed between them. Their encounters thereafter were always intense and violent.

During the Il Veltro incident, Chris was shown to be a generic and a typical "soldier", focusing only on the mission and disregarding his partner Jessica's advances. When asked by her whether he trusted her or not, he remarked "Trust is measured by actions, not words" to which Jessica replies "That's so like you, Chris. It's always about the job, isn't it?" Chris holds a level of professionalism; he never once berated Jessica for her flirting and simply focused on the mission. But, when Jill was in danger, he promptly switched his focus entirely into rescuing her.
During a BSAA mission to capture Ozwell E. Spencer, Jill sacrificed herself to save Chris from Wesker, while he was unable to protect Jill. Jill's perceived death was a very serious blow to Chris personally. Ever since that encounter, he became distant and cold-hearted. It also psychologically scarred him such as when Wesker opened the cargo door in the Stealth Bomber's cargo bay and Sheva Alomar was almost pulled out of the aircraft to her death. During the confrontation in the cargo bay of the bomber, Chris had a flashback of Jill's supposed death and how he was unable to do anything to protect Jill. This made him impulsively/instinctively endanger himself to not repeat the same mistake with Sheva.

In RE5 proper, Chris is initially shown to have a cold acceptance towards most of the grisly circumstances presented in the mission and shows little concern for its location or who he'll be working with.

Immediately after meeting Sheva, she asks him if he would "rather be in America than in a place like this".

Chris dismisses the notion, noting that America "has its own dark side". Sheva notes his lack of patriotism, and Chris merely states that he's a realist, noting that America is "a capitalist society" and that "not everyone is cut out for that kind of pressure". He considers that there are opportunities to be had, but as far as he sees it, "at a price". "If you gain, someone else loses."

When Sheva points out that he doesn't sound like any American that she's ever met, he responds with "The great thing about Americans is that we're all different".

Following the battle with the first Uroboros B.O.W. he and Sheva encountered, Chris mentions that if they had arrived sooner to assist DeChant and the rest of the Delta Team, they would've most likely been dead as well. A substantial part of his driving force during this time is seeking out Jill after he receives intel. The possibility that she might still be alive. Sheva has doubts about his "personal stake" in the mission, but later appreciates how much he cares for his old partner. With this, Sheva developed a close bond with Chris, deciding to stay and fight right alongside him to help him save Jill and takedown Wesker.
In episode one of the Resident Evil 5 viral campaign, entitled 'Ceremony', Chris is about to receive an award for his courageous performance in Kijuju, but is hindered from delivering his speech by a sudden onset of violent memories from his mission.

This could be considered as an indicator of post-traumatic stress disorder, which could plague Chris after the events of Resident Evil 5.

Chris's reactions to the various threats he has faced, vary over the years and change with his experience.

During his initial encounters with zombies and B.O.W.s in the Spencer Mansion, he was angered that it was all set up by Wesker (though in truth, the outbreak was caused by James Marcus; Wesker simply took advantage of the situation).

Following the events at Rockfort Island and the Antarctic Facility, Chris begins to categorize people like Albert Wesker into simple criminal personalities, refusing to acknowledge their views and immediately dismissing them as evil.

This is most apparent during his first encounter with Sergei Vladimir, where he refers to him as "another Umbrella psycho", despite the latter's various machinations since before the Mansion incident.

Chris then views Wesker's world plan in Kijuju with the same disdain. After he and Sheva board Wesker's stealth bomber, he is even sarcastic about the serious implications of Wesker's ambitions, going so far as to mock Wesker for taking his plans from "comic book villains" and dismissing him as "just another of Umbrella's leftovers."
