What do soldiers mean when they see officers salute? Who invented it and why? Is it to prevent the Fuehrer from being assassinated by soldiers when he sees that he has no weapons in his hand?

The origin of the hand-raising ceremony has not been verified, and there are usually two versions. One is that the soldiers of the Roman legion (or knights and warriors who participated in the tournament in medieval Europe) raised their hands to block the sun to show their respect for their superiors (or women who watched the tournament); First, it has the same intention as shaking hands, showing each other that they have no weapons in their hands. But it is more correct and well-founded that in medieval Europe, when knights met on the road, they would raise their helmets with their right hands to show their respect. This action later evolved into a hand-raising ceremony.

The common way to raise your hand in the world is to put your right hand with five fingers together and your palm flat, raise it to the position near your right eyebrow or right temple, and then put it down. In the armies of the United States, China and Russia, the palms are usually downward, while in Britain, the palms are forward. Most countries stipulate that soldiers can only raise their hands when wearing military hats, but the US Army, the China People's Liberation Army and other military forces stipulate that they can raise their hands with or without military hats. Polish soldiers salute with their right index finger and middle finger together and the other three fingers clench their fists.
