LINE I – This is the foundation of the entire LINE System and is what every other part is based off. Students are taught how to deal with grappling. It specifically aims to help practitioners with opponents that have their hand on you, whether standing or on the ground. It provides education in chocks, headlocks, and grabs can neutralize and/or lethally take out the opponent. For example, the main four techniques that are taught are front and rear chokes, along with front and rear headlocks. The whole idea behind LINE I is to get the person onto the floor and use the large muscle groups to bring the opponent to death through a grappling technique mentioned above or maneuvering so that important limbs can be crushed.
