From the front lines of Iraq and Afghanistan to here at home, soldiers blogging about military life are under the watchful eye of some of their own.
A Virginia-based operation, the Army Web Risk Assessment Cell, monitors official and unofficial blogs and other Web sites for anything that may compromise security. The team scans for official documents, personal contact information and pictures of weapons or entrances to camps.
In some cases, that information can be detrimental, said Lt. Col. Stephen Warnock, team leader and battalion commander of a Manassas-based Virginia National Guard unit working on the operation.
In one incident, a blogger was describing his duties as a guard, providing pictures of his post and discussing how to exploit its vulnerabilities. Other soldiers posted photos of an Army weapons system that was damaged by enemy attack, and another showed personal information that could have endangered his family.
"We are a nation at war," Warnock said by e-mail. "The less the enemy knows, the better it is for our soldiers."
