Appropriately for a Wired reporter, Joshua Davis has an interesting embedded report of the battlefield technology employed in Iraq. It didn't all go as smoothly as some reports would indicate.

"When we were deployed from the States," says Lieutenant Marc Lewis - the commander of the convoy's 27 heavy equipment trucks - "they told us that we would be given encrypted, military-issue radios when we got here. When we arrived, they told us we should have brought our own."

What Lewis brought was four Motorola Talkabouts, each with a range of about 1,000 feet. In the half-dozen convoy trips he's made since arriving in country, Lewis has taken to distributing a Talkabout to the first and last trucks. The other two go to vehicles at strategic points in between. It's hardly secure. Anybody with a radio could monitor the conversations.

Lewis is improvising as best he can. Before leaving the States, he bought a handheld eTrex GPS device, which he uses to track each of his forays into Iraq. In essence, he's created a map of Iraq's charted and uncharted freeways and desert roads. He just has no way to share it with anybody. But he is able to navigate as well as any of the tank or missile commanders he transported. I notice that at least four other soldiers in the convoy have brought their own store-bought GPS handhelds. These devices keep the convoys on track in lieu of having proper systems. "If we run out of batteries," Lewis says when showing me his map of Iraq, "this war is screwed."

I also liked his description of the use of commercial chat clients for secure communications.

Because anyone on Siprnet who wanted to could set up a chat, 50 rooms sprang up in the months before the war. The result: information overload. "We've started throwing people out of the rooms who don't belong there," Mims says.

"What's funny about using Microsoft Chat," he adds with a sly smile, "is that everybody has to choose an icon to represent themselves. Some of these guys haven't bothered, so the program assigns them one. We'll be in the middle of a battle and a bunch of field artillery colonels will come online in the form of these big-breasted blondes. We've got a few space aliens, too."
