The Boy Scouts of America is a youth organization that provides educational programs for boys and young adults. The organization is divided into four groups: DEN (3 letters), TROOP (5 letters), DENS (4 letters), and PACK (4 letters). A DEN is the smallest unit of the Boy Scouts, typically consisting of six to eight members. A TROOP is a larger group of Boy Scouts, usually consisting of 10-20 members. DENS are smaller subgroups within a TROOP, and Packs are larger groups of Boy Scouts, typically consisting of 30-40 members.
