Congress has mandated an annual report on street gang, outlaw biker, and domestic extremist activity in the military since 2008.

Jesse and Frank James were the most well-known military-trained gang members

Gangs have had connections to the U.S. Military in every period since the founding of the country.

Gang members have joined the military since the mid-1800s.

Members of every major street gang, outlaw biker, and domestic extremist group have been found in a number of military branches.

The first gang members who joined the military were known as the Hounds, a group of former New York gang members.

Military Veterans have become gang members since the late 1700s.

Only the Army conducts an annual assessment, and they appear to do relatively little to analyze the problem, contributions to the problem, and potential solutions.

The first military-trained gang member was Samuel Mason, leader of the Mason gang of river pirates operating along the Ohio River from the 1790s.
