Gang members in uniform use their military knowledge, skills and weapons to commit and facilitate various crimes. As of April 2011, the NGIC has identified members of at least 53 gangs whose members have served in or are affiliated with US military.

In 2006, Scott Barfield, a Defense Department investigator, said there is an online network of gangs and extremists: "They're communicating with each other about weapons, about recruiting, about keeping their identities secret, about organizing within the military."

A 2006 Chicago Sun-Times article reported that gangs encourage members to enter the military to learn urban warfare techniques to teach other gang members. A January 2007 article in the Chicago Sun-Times reported that gang members in the military are involved in the theft and sale of military weapons, ammunition, and equipment, including body armor. The Sun-Times began investigating the gang activity in the military after receiving photos of gang graffiti showing up in Iraq.

The FBI's 2007 report on gang membership in the military states that the military's recruit screening process is ineffective, allows gang members/extremists to enter the military, and lists at least eight instances in the last three years in which gang members have obtained military weapons for their illegal enterprises. "Gang Activity in the U.S. Armed Forces Increasing", dated January 12, 2007, states that street gangs including the Bloods, Crips, Black Disciples, Gangster Disciples, Hells Angels, Latin Kings, The 18th Street Gang, Mara Salvatrucha (MS-13), Mexican Mafia, Norteños, Sureños, and Vice Lords have been documented on military installations both domestic and international although recruiting gang members violates military regulations.
