Military officials have been wrestling for years with how to handle troops who publish blogs. Officers have weighed the need for wartime discretion against the opportunities for the public to personally connect with some of the most effective advocates for the operations in Afghanistan and Iraq -- the troops themselves. The secret-keepers have generally won the argument, and the once-permissive atmosphere has slowly grown more tightly regulated. Soldier-bloggers have dropped offline as a result.

The new rules (.pdf) obtained by Wired News require a commander be consulted before every blog update.

"This is the final nail in the coffin for combat blogging," said retired paratrooper Matthew Burden, editor of The Blog of War anthology. "No more military bloggers writing about their experiences in the combat zone. This is the best PR the military has -- it's most honest voice out of the war zone. And it's being silenced."

Nowadays, milbloggers "get shut down almost as fast as they're set up," said New York Army National Guard Spc. Jason Christopher Hartley, 31, of upstate New Paltz, who believes something is lost as the grunt's-eye take on Tikrit or Kabul is silenced or sanitized.

Hartley last January was among the first active-duty combat troops demoted and fined for security violations on his blog, justanothersoldier.com.

Throughout last year, the Army, Marines, Air Force and Navy tightened control on bloggers by requiring them to register through the chain of command and by creating special security squads to monitor milblogs.

"The ones that stay up are completely patriotic and innocuous, and they're fine if you want to read the flag-waving and how everything's peachy keen in Iraq," said Hartley, who is back in New Paltz after two years stationed in Iraq.

Some critics of the censorship say it could be harder for American soldiers to publicly raise questions about the U.S. invasion of Iraq, the success or failure of the war effort, and the "stop-loss" policy that forces soldiers to remain after enlistment contracts expire.

But a complete milblog blackout may never succeed.

"Is it over? No way, as long as there are soldiers and the Internet. People will always be starting blogs and get shut down, and then someone else starts one," Hartley said. "In my generation, or younger, everyone's all about spilling their guts on the Internet."
