From the BBC:
"Photos apparently showing German troops posing with a skull in Afghanistan have caused outrage in Germany.
The tabloid newspaper Bild, which carried the photos, says they show German troops in Afghanistan in 2003.
On one of the pictures, a soldier is seen holding the skull next to his exposed penis, on another - soldiers pose with the skull on their jeep.
German Defence Minister Franz Josef Jung expressed disgust at the photos and ordered an immediate investigation."
The Germans, it seems to me, given their history, have to meet the highest standard of behavior for their soldiers in combat. This is not a good sign.
