How does fatigue affect decision-making in defensive tactics?

• A. It has no effect on judgment or reaction time.
• B. It speeds up and sharpens situational awareness.
• C. It impairs judgment, reaction time, and situational awareness, increasing risk of error.
• D. It enhances vigilance during long shifts.

Answer: (C)

Fatigue degrades the mental processes and sensory awareness you rely on for quick, sound decisions in defensive situations. When you’re tired, information is processed more slowly, which hurts judgment about threats and the best course of action. Reaction time lengthens, so responses to changing danger come later, giving you less time to adapt. Situational awareness also suffers, with narrowed attention and missed cues, leading to a higher chance of misreading a scenario or overlooking important details. All of these combined increase the likelihood of errors under stress, making impaired judgment, slower responses, and reduced awareness a real risk when fatigue is present.
