Why is it important to cover with your left arm?

Covering with your left arm is crucial because it allows freedom of movement with the right hand. This positioning is especially significant in tactical scenarios, where the right hand may need to operate equipment, communicate, or respond quickly to threats while the left arm acts as a protective barrier. By keeping the left arm engaged in a covering position, the right hand maintains full functionality, which can be pivotal in dynamic situations.

When discussing other options, while improving balance might seem beneficial, it does not address the practical application of being ready to engage or respond. Similarly, although protecting the left side is a valid consideration, it doesn’t directly relate to the strategic advantage of having the right hand free to act. Finally, visibility, while important in some contexts, is less relevant to physical positioning in tactical movements. Therefore, having the right hand available for movement or actions upholds the primary benefit of this technique.
