Welcome to the next paid-subscriber release for Orders and Observations. This post includes two products:

  • C4ISR Brown Bag Session 4: Intelligence, Surveillance, and Reconnaissance (ISR)

  • ISR Sensor Phenomenology Field Guide v2.0

I plan to keep these paid drops on a steady cadence, schedule permitting. Expect the rest of the C4ISR primer series, more cheat sheets, and deeper analytic notes this month.

1) C4ISR Brown Bag Session 4: ISR

Session 4 explains what ISR is for and how it works in practice. It covers definitions and doctrinal anchors, the intelligence process and where ISR fits, TPED and PCPAD, collection strategy and revisit logic, and how ISR ties into joint targeting. It includes a quick tour of key U.S. organizations and tasking architecture, a brief comparison with PLA and Russian ISR, and a forward look at AI-enabled PED and assessment.
