Marines solidify ban on Facebook, Twitter

But for the military to be concerned about soldiers posting mission critical information on Facebook or MySpace, then they're not thinking broadly enough, van Wyk said.

"If they're concerned about the content, like soldiers posting, 'Wow, having breakfast just outside of Fallujah today,' then Facebook is purely just a scapegoat," he added. "Information can be shared in many different ways. SMS texts, for example. E-mails to friends. Facebook and its ilk make that particularly easy, as well as tough for the Marines to control or even monitor, but someone who wants to share information is going to find a way."
