I have a question dealing with Service Stars. When I was in Cub Scouts and Boy Scouts I received service stars. Now that I am a Cubmaster I am earning them. Do I just wear the one as a leader or do I also wear the one from my tenure as a scout? I wish there was a book or resource of every award and an explanation of what they are and how you earn them. It seems like most scout offices do not know what half the items are and where they go on the uniform or if they can go on the uniform. Thanks for any advice.
