A four star flag officer, I'm guessing.
Possibly General Fred Franks who lost his lower leg in Cambodia in 1970. He continued to serve and commanded the VII Corps in Desert Storm and later commanded U.S. Army Training and Doctrine Command as a four star.
I have a friend who lost part of his leg and right arm in Vietnam in 1971. He also continued to serve, participating in Desert Storm as the VII Corps G3, He is now 100% disabled and draws both military retired pay and VA disability. He served over 30 years. He does not draw Social Security Disability.
The article is incorrect in one aspect. I receive military retirement pay and VA disability, but my retired pay is decremented dollar for dollar. Those who receive both have a higher rated disability.
Except for the decrement of pay, retired pay and disability are not related. Qualifying for retired pay requires at least 20 years of active service. For every one of those years, you receive a document from finance reminding you that if you were in a civilian job, your pay would be X dollars higher to account for civilian retirement plans, 401K etc, plans that allow you to build equity over the years. No equity in the military until you cross the 20 year goal line.
