I've done that.
The first time I got in trouble in the Navy they gave us these little New testaments with Songs and Proverbs I think.
Anyway they were just big enough to put in a shirt pocket, but since you had so little storage there was no way I was keeping it, so I tore it in two and dropped it in the trash.
I was seen doing it and the next three hours I was in the Drill Instructors office being Christ shamed and demeaned.
They never gave me another bible and I still told them they were superstitious apes.
I had no friends.
I had three friends in the Army and two of them were nonbelievers and the third l had no idea what he believed.
