As Gen. Carlisle explained to Defense Tech:

The guys that were working down out of Hurlburt, they're combing through social media and they see some moron standing at this command. And in some social media, open forum, bragging about the command and control capabilities for Daesh, ISIL. And these guys go: 'We got an in.' So they do some work, long story short, about 22 hours later through that very building, three JDAMs [Joint Direct Attack Munitions] take that entire building out.
