Last year I was asked to shoot some promotional images for the U.S. Army Reserves; I tweeted about it at the time but never posted any of the images. Alenka posted a great series on her blog some time ago, which you should definitely check out.
This is my favorite shot from the trip, which is ironic in that the Army can’t use it—there’s no smoking allowed in the Humvees! Oops. So, it makes a good shot for my personal use.
