Some moments you have to act—and some moments you have to stop. Both require control.

During an intensive hostage rescue training program in England in the 1980s, David Burnell learned what it meant to commit fully when the signal came. Months of demanding exercises required attention, preparation, and the ability to move from readiness into purposeful action. But one of the most lasting lessons came when a participant continued fighting after the exercise had ended. A blank discharged toward Burnell’s face. Another student intervened and was injured protecting him.

The participant knew how to switch on. He failed to switch off.

That experience anchors this short, direct exploration of a quality elite operators must have: the ability to bring focused effort to a necessary task while staying responsive to changing conditions.

Drawing on that training and ten years developing the Urban Warfare Center, Burnell examines what switching on looks like physically, emotionally, and mentally. In plain language, he explores how stress affects attention and judgment, why determination cannot replace skill, and how training can prepare someone to act without surrendering control.

Switching on begins before physical action. It means bringing your attention fully to the environment, noticing sensory information, and taking a feeling of danger seriously enough to assess it. When action becomes necessary, readiness must become commitment. When the need changes, the response must change with it.

Through a continuous narrative, practical examples, and clear decision diagrams, Switch On considers how this principle applies to military personnel, law enforcement officers, and civilians facing a physical assault. Each has different responsibilities, abilities, and choices. The question remains: What does this situation require from me now?

The book also explores how to practice recognition, communication, commitment, and stopping—and why you may need to stop an action while your heart is still pounding and your emotions are still intense.

Grounded in lived experience and supported by carefully explained research, Switch On offers a focused look at readiness, decisive action, and the discipline to stop when the work changes.
