Hey, the veterans can get a special tombstone, and for the wife also. Granddad & Grandma has the white marble with the veteran's symbol on it. American Legion can easily spot them and put flags on the grave every Memorial Day without family being present every year.Family is getting smaller, less family where they are buried.
I think the modern way is to "plan" ahead and ease the burden of those left behind to worry about or have less to do. Often they write out their own obits, too.
