Technical Resources
Long-form technical references on the domains and engineering problems that define modern multi-domain operations.
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 explained: JDL/DFIG model, multi-INT disciplines, JADC2, and what fusion means for civilian operators.
What is Maritime Intelligence?
Maritime intelligence explained: AIS limits, dark vessels, beneficial ownership, sanctions risk, and multi-INT fusion at sea.
