"Army of Northern Virginia" (ISA nickname / Fort Belvoir base).
documentedsource_actorJSOC & Special-Access Units
Informal nickname for the ISA, reflecting its Fort Belvoir, VA headquarters and DC-area dispersed squadrons.
"The Army of Northern Virginia" is a documented informal nickname for the Intelligence Support Activity, alongside 'The Activity.' Its headquarters element sits at Fort Belvoir, Virginia, with squadrons scattered across the Maryland/DC/Virginia area; its SIGINT aircraft fleet was jokingly called 'the Confederate Air Force.' A naming/identity fact, not a distinct unit.
