There seems to be a DOD Reg covering this.However it does not cover civilians.
Right. Only military is covered by this. I was referring to it being proper to cross your heart when the flag is being raised, etc. for civilians. Undoubtedly not taught to a good number of the kids now days. Go to a sports event and when they raise the flag and play the National Anthem they stand there like a toad or laugh and play with their friends. My parents would have slapped me out of the seat if I had acted like that.
