Warning: Very Disturbing Photo – click link below to view.

Can anyone out there please explain this photo? I found it on the website of the Wall Street Journal’s Pictures of the Day. The caption reads as follows:

EATING SNAKES: Airmen ate snakes during a drill performed in front of students at a school in Sidon, Lebanon, Wednesday. (Ali Hashisho/Reuters)

WHY? WHY WOULD YOU DO THAT? WHAT’S THE POINT!!!

An explanation from anyone would be greatly appreciated!
