The three-finger salute is used by members of Scout and Guide organizations around the world when greeting other Scouts and in respect of a national flag at ceremonies. In most situations, the salute is made with the palm face out, the thumb holding down the little finger, and with the fingertips on the brow of the head.
Meaning of the three fingers
In his book, Scouting for Boys, Robert Baden-Powell chose the three-finger salute for Scouts to represent the three aspects of the Scout Promise:
1. Honour God and the King
2. Help Others
3. Obey the Scout Law
