From the Summary: "The Department of Veterans Affairs (VA) administers programs and provides benefits to qualified former U.S. servicemembers with service-connected disabilities (i.e., service-disabled veterans). These benefits can compensate a veteran for an injury or provide assistance to enable a veteran to have a higher quality of life. To qualify for benefits discussed in this report, a veteran must have a physical or mental condition that was 'incurred or aggravated' in the line of military duty that resulted in a disability. Service-connected disabilities are rated on a scale from 0% to 100%, in 10% increments, using a VA Schedule for Rating Disabilities (VASRD). Disability ratings are used to determine eligibility for various types of benefits and the amount of disability compensation benefits a veteran can receive. This report describes major VA benefit programs that are limited to veterans with service-connected disabilities."
