One of the members is Real Badman, a respected Jamaican gangster, and their businesses primarily consist of drug-trafficking (especially cannabis) and arms-trafficking. They have a concentrated presence in Broker and Dukes, in Schottler, Beechwood City and Willis, in various apartment complex, but mainly operate from the Homebrew Café in Beechwood City, Broker.
Jacob Hughes, a friend of Badman, a prolific arms dealer and a good friend of Niko Bellic, is a notable member of this crew.
The gang frequently clashes with other drug dealers in Broker and Dukes and employs hired guns like Niko Bellic to assist in these matters; additionally, Russian gangsters at one point attempted to intimidate Badman, hoping to absorb the Yardies’ operations; Badman responded by murdering the gang, with Niko's aid.
Yardies are Rastafarians; they speak Iyaric as well as patois, frequently smoke marijuana, and wear their hair in dreadlocks. They can be seen wearing brightly colored suits or army fatigues, and some wear Rasta tams, which is a sign of rudeboys style. They are well-armed, most members carrying pistols, or occasionally a knife or baseball bat. Their cars are painted in the colors of the Jamaican flag: green, black, and gold. They can mainly be found in the Beechwood City region, particularly the Homebrew Café, and have a smaller presence in neighboring Schottler and Willis as well.
Due to Niko being close friends with Little Jacob, the Yardies welcome him to their turf. If Niko is engaged in a fight, or is attacked by a Pedestrian, the Yardies will defend him by all means.
