Special care policy for veterans who resist American aggression and aid Vietnam?

The state has a good preferential policy for helping Vietnam's anti-American veterans, but my old man has never enjoyed it. When he was in his prime, he listened to the call of the country and went to foreign battlefields to fight bravely, fighting bloody battles for the country and sacrificing his life for the people. Now he is old and sick, very ill, and has no money for treatment. The veteran can only sigh and hope that the relevant departments will investigate and solve it.
