Worlds Deadliest Martial Arts
A close quarters combat style formerly used by various branches of the United States military, LINE Linear Infighting Neural Override Engagement includes death to one s opponent as the result of properly executed technique. Other aspects include its use in visibility impaired situations (e.g. nightime, smoke) and while under severe fatigue. Since LINE is meant to end an opponent s life, it was not useful in situations which did not require lethal force (e.g. peacekeeping missions); thus, the Marine Corps replaced LINE with the MCMAP (Marine Corps Martial Arts Program) in 2002.
