INTELLIGENCE DISCIPLINES

Intelligence is gathered, processed, and analyzed through distinct disciplines, each defined by the kind of source it draws on. The pages below introduce the core collection and counter-collection disciplines, written for the prepared citizen rather than the career analyst. Start with the discipline most relevant to your situational awareness needs, or work through them in sequence to build a complete picture of how raw information becomes actionable intelligence.

Signals-Based Disciplines

SIGINTSignals Intelligence (SIGINT)The parent discipline covering intelligence derived from intercepted signals, the foundation for COMINT, ELINT, and MASINT.
SIGINT · PrimerSignals Intelligence, the Basics (2020)The original introduction to SIGINT concepts and how intercepted signals reveal intent and capability.
SIGINT · PrimerSignals Intelligence, Information Gathering Basics (2022)An updated walk-through of practical signals collection and what it can tell a prepared observer.
COMINTCommunications Intelligence (COMINT)Intelligence drawn from intercepted communications: voice, text, and data exchanged between people and systems.
ELINTElectronic Intelligence (ELINT)Intelligence from non-communications electronic emissions such as radars, beacons, and other emitters.
TACELINTTactical Electronic Intelligence (TACELINT)Time-sensitive electronic intelligence supporting immediate, ground-level decisions and threat warning.

Technical & Measurement Disciplines

MASINTMeasurement and Signature Intelligence (MASINT)Intelligence derived from the distinctive measurable signatures of a target: acoustic, thermal, seismic, and more.
TECHINTTechnical & Infrastructure Intelligence (TECHINT)Intelligence about technology, equipment, and infrastructure: capabilities, vulnerabilities, and dependencies.
IMINT / GEOINTOverhead Imagery & Geospatial Intelligence (IMINT / GEOINT)Intelligence from imagery and geospatial data: overhead photography, mapping, and terrain analysis.

Open-Source Disciplines

OSINTOpen-Source Intelligence (OSINT)Intelligence assembled from publicly available sources: news, social media, public records, and the open web.
OSINT · AppliedHow to Conduct a Daily Threat Analysis Using OSINTA practical method for turning everyday open sources into a repeatable daily situational-awareness routine.

Surveillance & Counter-Surveillance

ESElectronic Surveillance (ES)How electronic means are used to monitor activity, and what that means for your own operational security.
Counter-SurveillanceElectronic Counter-SurveillanceDetecting, defeating, and defending against electronic surveillance and emission-based collection.

Applied Curriculum · The Architecture of IntelligenceThe Beaulieu MethodA defensive personal-security course built from the surviving SOE agent-technique syllabus, the same doctrine taught at Camp X. Eight modules turn observation, surveillance recognition, cover, and composure into trained instinct, with downloadable lesson plans and field cards for each.Open the course →

Human Intelligence

HUMINTHuman Intelligence (HUMINT)Intelligence drawn from people: observation, conversation, and reporting. The foundation behind community intelligence, area intelligence, and SALUTE/SPOT reporting.

Future & Under Development

The disciplines below round out the standard intelligence taxonomy. Pages are planned or in development and will be linked here as they publish.

CYBINTFutureCyber & Digital Network Intelligence (CYBINT / DNINT)Intelligence derived from cyberspace and digital networks: activity, intrusions, and indicators that complement the CYBERCON readiness picture.
FININTFutureFinancial Intelligence (FININT)Intelligence developed from financial activity and indicators, the collection discipline that underpins finance-sector threat reporting.

Where to go next: These disciplines feed the wider Intelligence Gathering & Analysis process.
