US Marines during a "monkey" drill practice! “Oorah!”

When in life, you are a Marine, athletic training must be accompanied by the coordination of movements combined with split-second timing.

The "choreography" for the drills is learned and practiced just like the marines train their muscles to perform at maximum efficiency.

In the video, the platoon performs what Americans call a "monkey" drill because it is completely improvised! Each marine must remember the calls and move instantly guided by the voice of the drill instructor! Amazing!  

Did they pass the "monkey" drill test? “Oorah!”
