Scouts

Boy Scouts, or more formally known as the Boy Scouts of America, was one of the largest youth organizations in the United States. Founded in 1910 as part of the international Scout Movement, it's goal was to train youth in responsible citizenship, character development, and self-reliance through participation in a wide range of outdoor activities, educational programs, and, at older age levels, career-oriented programs in partnership with community organizations.

Background
Every boy scout troop had a scout master and a group of boy scouts. They would go on trips occasionally, as seen by the crashed scout bus. It appears that there are people who knew about them, as Joshua Graham told Follows-Chalk about the scouts on the crashed bus, who thought he was talking about Dead Horse scouts, such as himself. By the time the Great War had happened, they were spread out across America. Boy Scout uniforms can be found in the Capital Wasteland and the Mojave Wasteland.

Appearences
Boy Scouts are mentioned-only in Fallout 3 and Fallout: New Vegas add-on Honest Hearts.
