The rank insignia system of the Indonesian Scouting movement Gerakan Pramuka is by and large militarized in traditions and outfit.
Much is left to the traditions of specific groups. Some of them do not grant some of the ranks to its members, while others name them differently; the very look of the insignia may differ from group to group.
Tanda Kecakapan Khusus (TKK) are merit badge awards earned by youth members of the Gerakan Pramuka organization, based on activities within an area of study by completing Special Skills Requirements (SSR/SKK). Some special TKK are also required in order to achieve the Eagle Scout award. Members who have earned more than five merit badges display them on a sash which may be optionally worn diagonally across the front of the Boy Scout uniform from right side to left side. Sashes are usually only worn for ceremonial occasions.
