Types of salutes

The French salute is almost identical to the British Army's.

The customary salute in the Polish Armed Forces is the two-fingers salute, a variation of the British military salute with only two fingers extended.

In the Russian military, the right hand, palm down, is brought to the right temple, almost, but not quite, touching; the head has to be covered.

In the Swedish armed forces, the salute is identical to that of the U.S. armed forces and the British Royal Navy.

In the Hellenic Army salute the palm is facing down and the fingers point to the coat of arms.
