There is a two-part word "Janbaz" (Persian جانباز) in Persian comprised of two parts i.e. Jan (i.e. life) + Baz (i.e. gamer) which refers to a former combatant who has sustained an injury during a war and is currently suffering from resulting disabilities. Is there a single English word used for such a person?

(literally) one who would offer up their life.

""Janbaz refers in Persian to someone who lays down their life for some cause. But in the post-revolution period it has been specifically used to refer to a disabled person from the Iran-Iraq War, and so I have given the equivalent of 'a disabled war veteran' for it."

"Disabled veteran" explicitly means the injury was permanent, while "Purple Heart veteran" explicitly means the injury was the direct result of enemy action. So if a combat veteran stubbed his toe while carrying ammunition, neither usage would be appropriate. In that case, then just "combat veteran" would be accurate.
