What do we owe veterans of an all volunteer armed force?

Considering that there is no draft and we currently have an all volunteer military, does the government owe veterans who are injured (or killed) on the job more than anyone else injured (or killed) on the job, say a police officer or fire fighter? Do we owe career armed forces veterans more than we owe career teachers, blue collar workers, nurses, or any other worker? Why or why not?
