WASHINGTON — US Army Training and Doctrine Command (TRADOC) officials are concerned about Wednesday's scheduled town hall style meeting on Facebook and Twitter, after reports of a planned terrorist attack have surfaced.

Sources say that "chatter" indicates ISIS and other Islamist groups may be threatening to unleash an Improvised Chat Device, or ICD, to disrupt the planned event.

Of particular concern to command leadership is the tactical hashtag "#talk2TRADOC."

"We've just learned to use social media," said a spokesman. "This hashtag was shared with Iraqi security forces and somehow wound up in the hands of ISIS. Now that it's been released, it's difficult to estimate what kinds of questions will be asked, or the damage that could be done by individuals with malicious intent."
