Is there financial assistance for veterans who served between active conflict?

No not eligible

You are correct, you never know and it doesn't hurt to research it.

Aid and Attendance is considered a pension. A person must have served "during wartime". Not actually was in the fighting but served. They can only get it if medically needed. Meaning your healthcare costs exceed your monthly income. So No, this pension your Dad can't receive. A regular military pension, you need to serve 20 yrs.

Your best bet is to call your County VA dept. and make an appt to talk to a rep. Have Dads records handy when you call because the rep may ask you questions when you call. I know a couple of men that served 2 yrs during Nam. Both fought in Nam for a year. They use the VA hospital as their secondary health insurance to Medicare. They use the VA doctors and services. Your Dad may not be able to get a pension but he may qualify for other services.

No But you should be talking to the VA instead of a caregiver forum.

As others have stated, check with the VA. I'm not sure that his service was long enough for a pension, though.

You would have to contact the va.

I want to take a moment here though to thank your father for his service. It is because of men like your father that my own father got to emigrate here.

Contact the VA administration, they will be able to give you a solid answer
