An impact-protected ruggedized Self Contained Breathing Apparatus (SCBA) instrumented with electronic and passive equipment so that the instrumented SCBA can be used in augmented reality-based training. The instrumented SCBA includes a breathing portion adapted to cover at least the user's mouth and nose, and a plastic shell covering at least some of the electronic and passive equipment from shock and environmental hazards. Mechanical devices couple the shell and the breathing portion. There is at least one resilient external member connected to the outside of the shell, to assist in the impact resistance of the shell.
