I have to post this: US Air Force Targets and Destroys ISIS HQ Building Using Social Media.
The short version is, an ISIS fighter posted a selfie on social media and was boasting about the "command-and-control" capabilities of the building he was in.
We saw it and extracted the EXIF data from the selfie, which gave us the exact location of said command-and-control bunker.
22 hours after he posted his selfie, 3 JDAMs (Joint Direct Attack Munitions, GPS guided 1,000+ pound bombs) penetrated the roof of the building, wiping it from the face of the earth.
Just remember that whenever you post a selfie.
