As a military man I happened to get my hand in the creation of my ID Tags

Under the religious preference line I put NONE. Anyone else done this? My family is highly Southern Baptist so they do not know this. If I'm ever KIA it'll be a surprise, however I need new "dog tags" so I am thinking of putting a "Z?" or scratching a BA picture there. but purpose of this post, anyone else put NONE on that line and do your folks know?
