• Our History.

Heeding the nation's call to defend cyberspace, U.S. Army Cyber Command was established in 2010. Upon activation it was aligned with Second United States Army, a proud fighting force with its roots in World War I. Second Army was inactivated in 2017, but ARCYBER continues to carry its values and fighting spirit into today's missions in the cyber domain.
