Last June, the Chairman of the Joint Chiefs of Staff issued a classified “execute order” to authorize and initiate a military operation.
The nature, scope and duration of the military operation could not immediately be determined — even the title of the order is classified — but it evidently pertains to the conduct of military cyberspace activities.
The existence of the previously undisclosed execute order was revealed last week in a new Air Force Instruction.
I'm guessing some sort of retaliation against China, since there were so many stories about Chinese operations in early-mid 2013, and Tom Donilon started asking China to stop without actually accusing the Chinese government of doing it. I thought those were about making CISPA look more attractive at the time, but if the Pentagon decided to crack anyone around then China looks most likely.
