US Air Force warns troops about Facebook feature
None
The Air Force is warning its troops to be careful when using Facebook and other popular networking sites because some new features could show the enemy exactly where US forces are located in war zones.
In a warning issued on its internal website earlier this month, the Air Force said that "careless use of these services by airmen can have devastating operations security and privacy implications." The message was also sent to senior commanders, who were asked to get the word out to their forces. (AP)
