What is an example of a Protective Measure for Military Operations (PMM)?

The correct choice in this context reflects the concept of minimizing risks associated with military operations through environmental adaptations. Tuning a vehicle outside serves as a protective measure as it targets potential hazards, ensuring mechanics can address vehicle performance without the risk of exposure to harmful fumes inside a confined space. This practice integrates safety into routine operations, safeguarding both personnel and equipment.

While regular equipment inspections, safety protocols, and training personnel on hazardous materials are vital elements of operational safety, they do not directly relate to specific adaptations made in the operational environment like tuning a vehicle outside does. Those measures focus on maintenance and protocol establishment rather than immediate risk reduction associated with surroundings during military operations.
