What is referred to as the reactionary gap?

The reactionary gap refers to the physical space between an officer and a subject that allows the officer to effectively respond to any potential threats from that subject. Maintaining this distance is crucial because it provides the officer with enough time to assess the situation, evaluate any potential risks, and decide on an appropriate course of action, whether that involves issuing commands or taking more direct action if a threat is perceived.

This concept is foundational in law enforcement and military training, applying not only to physical confrontations but also to preserving personal safety and the safety of others in potentially dangerous situations. By keeping a proper reactionary gap, officers can better protect themselves and remain prepared to respond as necessary when engaging with a subject.
