The Explorer Scout program was built around the idea of advanced outdoor activities, going beyond what a 12/13 year Boy Scout could do.
This concept is what inspired the advancement and uniform of this program.
Badges awarded by organizations other than the boy Scouts of America may not be worn on the official uniform.
(Exceptions: Historic trails medals and religious emblems.) See Rules and Regulations of the Boy Scouts of America and the Insignia Guide for additional information on uniform rules and regulations.
My father is a lifelong Boy Scout, and when I was a child he insisted that I join scouting, too.
