Yes. While the ADA prohibits discrimination against qualified people with disabilities, it does not prevent an employer from having a preference for one potential employee over another.
In fact, the U.S. government, in coordination with several veteran organizations, actively encourages employers to make room for one of the many veterans who were injured while serving the country. There are specific rules and regulations that govern hiring veterans by federal employers and detail what is considered a veteran’s preference, which is given to all veterans, including those who are disabled.
