My former boss did a stint in Baghdad, as a civilian (Corps of Engineers), and he wrote us about the races they'd have, at that time the civilians could run in typical running gear, but their body guards would run in full battle dress, trading off as the race around the Green Zone would progress. He was humiliated and in total awe at being passed by a woman soldier/guard. Just when you think you're hot stuff, being passed by someone wearing an extra 45 pounds...
