This picture of US troops trying out a new game for physical training. It's called mortarball. They use a reduced charge to propel the ball at a low enough speed so as to be able to hit it with the bat. An earlier try came to an unfortunate end when a full charge was used. However, the trooper, now called "Lefty" is doing well in a hospital in Germany and should be able to return to duty in a week.
Aloha!
