Help to find an old film please.

Many years ago on a film magazine program called “Cinema? there was an extremely haunting scene shown. It was set in a wide-open space, possibly a frozen lake, dry lakebed, or desert.

There were a group of soldiers, an officer, and a young woman.

The officer ordered the women to walk away into the distance and after a short while he turned to one of the soldiers and asked for his rifle.

He took careful aim and fired and the woman dropped to the ground.

Any ideas?

Thanks piroflip2
