Apparently there's been a rash of fraudulent text messages informing recipients that they have been drafted in the United States Army and they should call the recruiting office immediately. I'd bet that the phone number is actually an international toll call and most of the fees go to the scammer, like the common "one-ring call" scams. From the US Army Recruiting Command:
The decision to enact a draft is not made at or by U.S. Army Recruiting Command. The Selective Service System, a separate agency outside of the Department of Defense, is the organization that manages registration for the Selective Service.
"The Selective Service System is conducting business as usual,” according to the Selective Service System’s official Facebook page. “In the event that a national emergency necessitates a draft, Congress and the President would need to pass official legislation to authorize a draft."
And of course that's highly unlikely, right? RIGHT?!?
