This from Steve Redick:
Had an amazing opportunity recently. I was able to get a shot of the entire 1st battalion assembled at the end of navy pier. This was an apparatus maneuvering and spotting drill and resulted in what I feel is a once in a lifetime shot. All of the members assigned to the units are in the image as well. The full size image has just enough resolution to be able to identify most of the people in the photo. Both boats positioned very well in the background as well as a bit of skyline round it all out.
