When selecting a training site for live fire exercises, which factor is least important?

When choosing a training site for live fire exercises, the local population density is the least important factor in comparison to accessibility, safety features, and compliance with regulations. The primary focus for live fire training is to ensure that participants can conduct their exercises in a safe and controlled environment, which heavily relies on the available safety features and the site's compliance with local regulations.

Safety features available on-site, such as available emergency services, the design of the range, and barriers, directly impact the ability to manage risks associated with live fire exercises. Similarly, compliance with local regulations ensures that the exercise meets legal and safety standards, further minimizing potential hazards.

While accessibility is more significant due to logistical considerations and the ability for personnel and equipment to reach the site effectively, local population density, while still relevant, doesn't have the same direct impact on the immediate safety and regulatory compliance aspects critical to live fire training. Essentially, ensuring a safe environment and adhering to regulations take precedence over how densely populated the surrounding area is, making it the least important factor in this context.
