I've been doing some IPB on a new AO, and have been using a massive amount of OSINT to do it. I balance it out with the classified stuff I get, but for the most part, between media from the region, media in the US, and scholastic reports on the history of the AO, I have a much better overall understanding of the AO and can convey that to my commander. I am definitely an OSINT convert after these past two weeks!
