I found this while exploring old photos I inherited in a box from family. It was a photo that belonged to my grandmother. After some discussion with other family members, we are fairly certain that at least one of these men must be my great grandfather (that grandmother's father) when he was a soldier stationed at Camp Meade in MD (nowadays known as Fort Meade, of course).

This is the same photo after I cropped and played with it a bit. I was trying to draw out more detail.
