Mozambique Drill
The Mozambique Drill, also known as the Failure Drill, or Failure to Stop drill, informally, "two to the body, one to the head," is a close-quarters shooting technique that requires the shooter to fire twice into the torso of a target (known as a double tap or hammered pair to the center of mass), and follow up with a more difficult head shot that, if properly placed, will instantly stop the target if the previous shots failed to do so.
