The Mozambique Drill,[1] also known as the Failure Drill, Failure to Stop drill, or informally as "two to the body, one to the head",[2][3] 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 shot to the head that, if properly placed, should kill or otherwise stop the target if the previous shots failed to do so.[4][5][6]
Head. A bullet through the brain has a similar effect as turning off a light. The opponent will immediately cease all action and will have no involuntary muscle contraction, provided that the shot was properly placed. This is known as the "Immediate Incapacitation Shot" and is highly successful. The shooter must place the shot directly through the "T-Box". The "T-Box" is the area that encompasses the nose and eyes. At 25 yards the shooter will need to acquire sight picture directly between the eyebrows.
