G-Unit is an American hip hop group originating from New York City. G-Unit emerged on the New York scene by independently releasing several mixtapes. The name of the group is short for Guerilla Unit as well as Gangsta Unit.[1]

In 2003, the group's debut album, Beg for Mercy, was released. However, whilst the album was being recorded, Tony Yayo was sentenced to jail on charges of gun possession. Therefore, he only makes two appearances both on pre-recorded tracks. His face is seen on the brick wall of the album cover because he could not be photographed on account of his jail sentence. Beg for Mercy sold 2.3 million copies in the U.S. and 4 million copies worldwide[7]. The only featured guest on the album was R&B singer, Joe. Production came from Hi-Tek, Dr. Dre, Scott Storch as well as others.
Their second album, T.O.S: Terminate on Sight, was released on July 1, 2008.[13][14] While the album was being recorded, internal conflicts arose between Young Buck and 50 Cent, which resulted in Young Buck being kicked out of the group, but still signed to G-Unit Records.[10] Young Buck still appeared on songs previously recorded with the group, but was credited as a featuring artist. As of August 8, 2008, the album has sold 185,000 copies in the United States.[15][16] Along with Young Buck, Mavado guests on the album, while production came from Swizz Beatz, Tha Bizness, Rick Rock, Polow da Don and others.
