Both of my grandfathers went I.O. initials only, including when they were drafted for WWII. One would use his first name about half the time, but only reveal what the middle initial stood for maybe twice in my lifetime. The other: I.O. all the way, to his grave nobody I know ever heard what those initials stood for.
