How does the NSA use the information it sucks up from around the world? There are probably lots of programs we won't ever know about, but we can be certain that the agency uses its formidable communications collections capabilities to assist the military (including JSOC) and the CIA in foreign targeting operations.
A 2010 email from a Stratfor analyst, released by Wikileaks, suggests the NSA is also training foreign militaries in intelligence collection:
The Yemeni CT units are slowly (well, trying) to come up to speed. There's a body that was created about a year ago, called the OSSF – office of strategic security forces or something like that. It's 100,000 strong, trained by Jordanian and US intel, NSA. There's a change in attitude by Sanaa on the CT front. Whereas before, the US would provide the coordinates on a target and the Yemenis would stall and stall, now they're ready to take them out.
