HISTORY OF THE MILITARY SALUTE
Men of arms have used some form of the military salute as an exchange of greeting since the earliest times. It has been preserved and its use continued in all modern armies which inherit their military traditions from the age of chivalry. The method of rendering the salute has varied through the ages, as it still varies in form between the armies of the world today.

When two friendly knights met, it was the custom for each to raise the visor and expose his face to view of the other. This was always done with the right hand, the left being used to hold the reins. It was significant gesture of friendship and confidence, since it exposed the features and also removed the right hand - the sword hand - from the vicinity of the weapon. Also, in ancient times the freemen (soldiers) of Europe were allowed to carry arms; when two freemen met, each would raise his right hand to show that he held no weapons and that the meeting was a friendly one.
Slaves were not allowed to carry arms, and they passed freemen without the exchange of a greeting. In the Middle Ages, gentlemen often went about clothed in heavy capes under which swords were carried.
Upon meeting a friend, the cloak was thrown back by raising the right arm, thus disclosing that the right hand was not on the sword hilt. The civilian counterpart of the salutes manifested in various ways such as raising the hand when greeting a friend, tipping the hat when meeting a lady, and using a sign of recognition between lodge members. This sign is always exchanged as a greeting between friends and is
