# Military Intelligence
## Definition
Military intelligence is the collection, processing, exploitation, analysis, production and dissemination of information needed to support defense policy, force protection, planning, targeting, readiness and military operations. It includes tactical, operational, theater, strategic, scientific-and-technical, counterintelligence, cyber and security functions.
## United States Architecture
“Military intelligence” is larger than the [[wiki/Defense Intelligence Agency|Defense Intelligence Agency]]. DIA is a defense combat-support agency; each armed service also has an intelligence enterprise, and intelligence personnel are embedded throughout commands and operational formations. The [[wiki/United States Army Intelligence|Army]] is especially large because ground forces require intelligence across echelons, geographic theaters and installations.
The Army's public enterprise description connects national and tactical intelligence and spans collection, processing, exploitation, analysis and dissemination. [[wiki/Army Intelligence and Security Command|INSCOM]] is its largest operational command, but the enterprise also includes the [[wiki/Military Intelligence Corps|Military Intelligence Corps]], [[wiki/Deputy Chief of Staff G-2|Army G-2]], tactical units, Reserve and National Guard components, cyber forces, counterintelligence and training institutions.
## Counterterrorism and the Domestic Infrastructure Layer
Military intelligence contributes foreign-threat analysis, force protection, identity intelligence, biometrics, SIGINT, GEOINT, HUMINT, MASINT, aerial ISR, cyber operations, partner support and operational targeting. Its domestic importance is not measured only by whether soldiers make civilian arrests. Bases, networks, reachback centers, counterintelligence offices, cyber forces, sensors, laboratories and analysts inside the United States are part of the infrastructure through which threats are detected, attributed, defended against and shared.
That is especially true for [[wiki/Cyberterrorism|cyberterrorism]], where the contested object is often infrastructure itself. A domestic effect may originate abroad, cross commercial networks, touch Army or DoD systems and require civilian investigation, military cyber defense and intelligence support at the same time. The FBI's investigative primacy and military support can therefore coexist. The oath to defend the Constitution against enemies foreign and domestic states the service obligation; specific collection or action still depends on lawful authority.
## Pantheon Interface
Chanda's S1E6 recipient list deliberately includes military and foreign-intelligence institutions. “Government” is not one operational actor; capabilities move through departments, services, liaison arrangements, command structures and classification systems.
