Well into my tour while rolling down the road in a Humvee (HMMWV), eating a mostly melted Kit-Kat and minding my own business...I saw a flash to the front and left of me on the other side of a passing fuel tanker in a convoy going the other direction. The tanker was entirely ripped open and a good deal of the fuel caught fire in the air and blossomed orange. My initial thought (in deployment language) was, "Jesus, that's fucking beautiful! And I'm fucking alive! This wind feels amazing! This is the most delicious Kit-Kat I've ever fucking eaten!!" Odd thoughts, I know. My TC (truck commander) who was also my LT (lieutenant) was feverishly reaching back, trying to pull me down into the truck. A few seconds later my truck was hit with a torrential downfall of extraordinarily hot diesel fuel, and I was entirely soaked. Diesel in my eyes, mouth, ears, and nose. I rode like that for hours with burning eyes and skin and a splitting headache. I never did think about the guy in the other convoy that got hit, I just knew it wasn't us and that's what I cared about. My LT said that was the first time anything there felt real. Total time, maybe 15 seconds.
