Reuters: Military personnel on non-classified networks will now be able to access Twitter, Facebook, and other social networking and Web 2.0 sites. Some commands, particularly Marine commands, had banned access to the sites because of security or bandwidth-usage concerns.
"The purpose of the policy is to recognize that we need to take advantage of these Internet-based capabilities. These Web 2.0 tools need to be part of what we use," said David Wennergren, a deputy assistant secretary of defense.
Commanders still have the ability to ban access to social media if bandwidth is overwhelmed or in advance of major offensives.
