Date of Publication:



Any impairment due to disease or injury, regardless of degree, that reduces or prevents an individual’s actual or presumed ability to engage in gainful employment or normal activity. The term “disability” or “physical disability” includes mental disease, but not such inherent defects as developmental or behavioral disorders. A medical impairment, mental disease, or physical defect standing alone does not constitute a disability. To constitute a disability, the medical impairment, mental disease, or physical defect must be severe enough to interfere with the service member’s ability to adequately perform his or her duties.
