From the BBC (link to article):
US forces in Afghanistan are checking reports that stolen computer hardware containing military secrets is being sold at a market beside a big US base.

Shopkeepers at a market next to Bagram base, outside Kabul, have been selling memory drives stolen from the facility, the Los Angeles Times newspaper says.

The disks reportedly contain personal details about US soldiers, military defences and lists of enemy targets.

Hard Drive Encryption anyone?
