You never worked in Iraq then, because it was common usage to use personal and government flash drives on government computers during that time. Personal flash drives were not prefered, however they were still used by many indivisuals, myself included. Now they are banned by the local IT policy, as far as DOD or DA policy I don't know what the current policy is. The problem is that a flash drive that was not supposed to be on the classified network, was used on a classified machine and you know the rest.
