" While the train pauses.."
Some moments are not always special, and one does not realize any special importance to capture it, or make it last. Just like when the trains stops on the tracks and pauses for a while. One soldier though, grabbed his camera and took the opportunity to make some photos.
I like these special moments of "non-importance" because this is what military and ordinary life contains, and it gives a special touch of regularity amongst more important moments in history.
