US Army ATP 2-22.9: Open-Source Intelligence
Headquarters, Department of the Army
US Army doctrine defining OSINT, its process, and classification handling, aimed at soldiers rather than analysts. The 2012 edition is public; later editions are restricted, and the current publication has a new number. Read it for definitions.
The 2012 ATP 2-22.9 replaced an earlier field manual interim and was approved for public release. A 2017 edition carried a distribution restriction and was released under freedom-of-information requests. The Army's current publication is ATP 2-22.9-1, Publicly Available Information Research and Open-Source Intelligence, from 2023 with a 2025 change, alongside a classified second volume. Only the 2012 text is clearly public, through the Federation of American Scientists.
The 2012 edition is superseded twice over, and the mirror blocked automated access when we checked. It remains the one clearly public edition and is widely cited for the US Army definition of OSINT.

- You work with military or government partners and want their vocabulary
- You are interested in how over-classification of public material is handled
Skip it if
- You want techniques; it is doctrine
- You need the current edition; it may not be publicly available

How current it is
The 2012 edition is superseded by a restricted 2017 edition and by ATP 2-22.9-1 in 2023 with a change in 2025. Whether the 2023 publication is downloadable from the Army is unverified. The Federation of American Scientists write-up from 2012 called it remedial in places.

FAQ
Questions, answered
Is the current edition public?
Unclear. The 2023 ATP 2-22.9-1 is listed as active by the Army Publishing Directorate; whether its PDF is downloadable without restriction could not be confirmed. The second volume is classified.
Why is it listed if it is superseded?
Because it is the edition people cite and the only one clearly public, and because the definitions have not changed much.
