John "Hannibal" Smith is the leader of the A-Team. He is a brilliant tactician and a master of disguise. Hannibal is distinguished by his cigar smoking, black gloves, disguises, and his catch phrase, "I love it when a plan comes together." Always "on the jazz" (a phrase coined by B.A., meaning that Hannibal thrives on adventure and life-threatening situations), he seems to genuinely enjoy every situation they get into. He also works as an actor, playing monsters in low-budget horror movies. He is portrayed by Liam Neeson in the film adaption.
Templeton "Face(man)" Peck was suave, smooth-talking, and hugely successful with women who serves as the team's con man and scrounger, as he is able to get his hands on just about anything they need. Effectively second-in-command behind Hannibal (although Murdock outranks him), he is the one who arranges for supplies, equipment, and sensitive information using numerous scams and hustles. Tim Dunigan played this role in the pilot episode, and Bradley Cooper in the film adaption.
Bosco "B.A." Baracus is a highly skilled mechanic and the A-Team's regular Mr. Fix-It as well as being the teams master at arms. His character is basically that of the public persona of Mr. T himself. He is a skilled fighter and is easily roused to anger, earning him the nickname "Bad Attitude". Despite his reputed attitude, he is a nice guy at heart. He has a special fondness for children and never drinks alcohol, preferring milk instead. He is most upset by Murdock, frequently referring to him as a "crazy fool". He suffers an intense fear of flying, especially when the plane in question is flown by Murdock. This difficulty is often overcome by other members of the team drugging him, or otherwise rendering him unconscious, so he can be transported without objection. He is portrayed by Quinton "Rampage" Jackson in the film adaption.
Howling Mad Murdock was the best chopper pilot of the Vietnam War who is either mentally unstable or exceptionally good at pretending to be so. Although he was their pilot on the Hanoi bank raid, he was not officially part of the A-Team and so not tried by the military. Though interned at a psychiatric hospital, he routinely escapes to accompany the A-Team on their missions. The symptoms of his "insanity" varies from episode to episode, but generally includes self-identification with fictional characters, hallucinations, belief in the "intelligence" of inanimate objects, among others. He frequently refers to his invisible dog, "Billy". Unlike B.A., the initials "H.M." were never explained in terms of Murdock's actual name, and the nickname "Howlin' Mad" is simply attributed to him. He was permanently discharged from the hospital in the fifth season. He is portrayed by Sharlto Copley in the film adaption.
