What is considered a low-level restraint technique that can also render a high-level subject unconscious?

The shoulder pin restraint is recognized as a low-level restraint technique due to its primarily controlling nature. This technique involves using body weight to immobilize an individual by pinning their shoulder to the ground, allowing for the control of movement while minimizing the chances of injury. Its effectiveness can be heightened when applied correctly against a high-level subject—meaning someone exhibiting significant resistance or aggression.

When performed properly, such restraint can restrict blood flow to the brain, potentially rendering an individual unconscious without requiring excessive force or aggressive maneuvers. This capability makes it distinct among similar techniques used in various restraint situations, illustrating a balance between control and safeguarding both the subject and the individual applying the restraint.

Conversely, the arm lock maneuver typically focuses on joint control, and while it can incapacitate, it is not inherently designed to render someone unconscious. The finger strike, while a technique that may cause pain or distraction, is less about control and more about striking, making it not suitable for unconsciousness. Thus, the shoulder pin restraint stands out as the appropriate choice in this context.
