I can tell you:
it was night/there was full moon/you have a pack of cards in your left chest pocket/a med pack in your right pants pocket/you are right handed (or maybe, but not likely, ambidexterous)/you have brown hair/brown eyes/are probably about 6'1"/that is your "game" face/you weren't out playing yet/you weren't diving around the time (before) the picture was taken/you were around a town (within 2 miles)/you were probably in a desert or dry climate/ it was a practice run/you have a leave behind in your ruck/you only have one glove...(I am thinking either because the shells are hot and fly out and hit your hand and because you need the other hand free to pick stuff up)/you have something in your left pants pocket....hhhmmmm
how's I do?
