Which program disqualifies individuals with defective color vision?

The correct program that disqualifies individuals with defective color vision is the Unrestricted Line (URL) Program. This is because specific roles within the URL, particularly in naval aviation and surface warfare, require precise color discrimination for safety and operational effectiveness. For instance, pilots must interpret various visual signals and navigation aids, which could lead to dangerous situations if color vision is impaired.

In contrast, the other programs listed typically do not have stringent color vision requirements. The Pilot Program has its own set of criteria for selection, but not necessarily focused solely on color vision. The Medical Enlisted Commissioning Program, while rigorous in its medical standards, may accommodate certain visual deficiencies under specific conditions, depending on the role. Lastly, the Legal Officer Program generally emphasizes educational and legal qualifications more than physical or medical disqualifications. Thus, the URL Program stands out for its strict adherence to color vision requirements.
