Which best describes the reaction time principle in defensive tactics?

• A. The amount of time it takes for the brain to process a physical threat and the body to respond, including perceiving threat, analyzing it, formulating a strategy, and initiating motor action
• B. The time it takes to call for backup
• C. The time needed to file a report
• D. The time required to de-escalate verbally

Answer: (B)

Reaction time in defensive tactics is the interval from threat detection to initiating a physical response. It includes perceiving the threat, analyzing it, deciding on a course of action, and beginning to move. This full sequence best fits the concept because it describes the cognitive processing and the motor action that must occur before you actually respond. Tasks like calling for backup, filing a report, or verbally de-escalating are important parts of a response, but they are not the measure of reaction time itself; they occur at different stages and aren’t the core focus of the reaction-time concept.
