There was some routine foot traffic that day, and I was the NCO on watch that morning. It was a bit before 1100, and we were expecting a convoy coming...through mid-afternoon from Anaconda Two. The Iraqi Army outposts were both manned, but understrength, which was nothing new. They were letting foot traffic through, along with pushcarts, but no vehicles.

I said placing my hand on her leg and stroking the inside of her thigh.I can't this is just too weird. I'm not like this and it's already gone too far today. I can't even believe we are having this conversation." She said her eyes pleading with mine."We're on vacation sweetie..
