The Defense Intelligence Agency or DIA was a United States secret intelligence agency before the great war. It specialized in counterintelligence operations both domestic and abroad.
It was created in 1961 to deal with potential communist threats. It being a fairly new organization meant it could escape the limelight and focus on its operations more.
The headquarters are based in Joint Base Anacostia–Bolling, Washington D.C. but it has numerous bases within and outside the U.S.A.
These bases include: The Switchboard in Lexington, Massachusetts of the New England Commonwealth and the Naval Recruiting Center on Point Lookout, Maryland of the Columbia Commonwealth.
It disappeared along with the majority of other government bodies when the great war broke out.
