Technical Resources
Long-form technical references on the domains and engineering problems that define modern multi-domain operations.
What is ATAK?
ATAK explained: TAK clients, EUDs, data packages, mesh networks, federation, plugins, and the CoT protocol that ties it together.
What is a Common Operational Picture (COP)?
COP in the military means Common Operational Picture: a shared, real-time view of friendly, neutral, and threat forces. What it is and why most fail.
What is EMSO (Electromagnetic Spectrum Operations)?
EMSO (Electromagnetic Spectrum Operations) meaning: how the military exploits, attacks, protects, and manages the EM spectrum, from EW to EMBM and EOB.
What is JADC2 (Joint All-Domain Command and Control)?
JADC2 explained: the DoD strategy, its five lines of effort, CJADC2, service programs, DDIL, and the technical building blocks of all-domain C2.
What is Sensor Fusion?
Multi-sensor fusion explained: Kalman and IMM filters, data association, MHT, track management, time alignment, registration, and track-to-track fusion.
What is Digital Force Protection?
Digital Force Protection explained: countering ubiquitous technical surveillance through device census, co-traveler analysis, signature management, and fused defensive measurement.
What is Intelligence Fusion?
Intelligence fusion meaning: combining sensor, signal, human, and open-source data into one decision-ready picture. JDL/DFIG levels, multi-INT, and JADC2.
What is Maritime Intelligence?
Maritime intelligence explained: AIS limits, dark vessels, beneficial ownership, sanctions risk, and multi-INT fusion at sea.
What is OPSEC?
OPSEC, UTS, and Digital Force Protection explained: the five-step process, five threat vectors, and signature management.
What is Counter Threat Finance?
Counter Threat Finance (CTF) explained: DoDD 5205.14 doctrine, CTF vs. AML, sanctions, shell companies, TBML, and operational software.
What is Entity Resolution?
Entity Resolution explained: deterministic, probabilistic, ML, and graph methods for matching records to real-world identities.
What is Narrative Intelligence?
Narrative Intelligence (NARINT) explained: detecting and countering influence operations, DISARM framework, CIB, and OSINT.
What is Space Situational Awareness?
Space Situational Awareness (SSA) explained: orbital tracking, TLEs, the Space Surveillance Network, and counterspace threats.
What is Counter-UAS?
Counter-UAS (C-UAS) explained: sensors, fusion, effectors, legal authorities, and layered drone defense for military and critical sites.
