In which American TV series does Sergeant Baracus appear?

Sergeant Bosco Albert "B. A." (Bad Attitude), played by Mr. T, is a fictional character and one of the four protagonists of the 1980s action-adventure television series "The A-Team". B. A. Baracus appeared on The A-Team from the series beginning in 1983 until its cancellation in 1987. He is arguably the breakout character of the series and has become a cult icon worldwide.

"The A-Team" is a group of ex--United States Army Special Forces soldiers who were wrongly convicted of a crime during the Vietnam War. Managing to escape from the Military Police, they fled to Los Angeles where, as fugitives, the A-Team works as soldiers of fortune, using their military training to fight oppression and injustice. B. A., along with Hannibal Smith, Templeton "Faceman" Peck, and H. M. Murdock make up the A-Team.

In the pilot episode, "Mexican Slayride", B. A. is described as follows by a reporter colleague of Amy Allen: "Bosco Baracus. Known as B. A. for 'bad attitude.' The man is a mechanical genius. He also has one of the worst conduct records in the army. He likes to slug officers." A rough-and-tough fighter, the character of B. A. Baracus is basically that of the public persona of Mr. T himself. He is known for his trademark African Mandinka warrior hairstyle (often mistaken for a mohawk hairstyle), and his gold jewelry.
