Which of the following would qualify as a qualified hazard duty area?

A designated area with imminent danger pay qualifies as a qualified hazard duty area because it is specifically recognized by the military as a location where service members are at risk of physical harm due to hostile activities or environmental conditions. This designation is connected to entitlements and special compensation for those who serve in hazardous environments, reflecting the increased risk involved.

The other options do not meet the criteria for a qualified hazard duty area. Military bases within the U.S. may not always present imminent danger and typically do not qualify for such pay. Locations outside the U.S. without any military presence would not meet the necessary conditions for being designated as a hazard duty area, as there would be no operational context or risk associated with them. Lastly, simply being stationed in any area does not automatically qualify it as a hazard duty area unless it is specifically designated for imminent danger pay.
