You should head over to The Desert Periscope and meet Dan, a submarine officer just over halfway into a 1 year IA tour in Iraq. Chapomatic just mentioned him, but looking through the sub-blogosphere, I notice quite a few other guys already had him blogrolled.
Speaking of submarine blogrolls, I somehow neglected to put LazLong and Ramblinboy on mine during the last few months. I shall rectify that shortly.
