Regarding armor and firearms, the revolutionary teacher has a famous argument: "Gunpowder blows up the knightly class", which is correct under most premises, but there are always some people and equipment in history who are not willing to be crushed by the wheels of history, but want to survive and fight against the revolutionary teacher. For example, the famous Knights Hospitaller firearms were playing thief, and they could continue to fight after the founding of the United States in 1784, attacking the North African pirates in Algiers with cannons. Other armors stubbornly survived the war until the end of The First World War.
In the Western, many protagonists and villains have plate armor protection, the most typical example is the villain Raymond in "Red Dead Redemption", and the protagonist Joe has to use similar equipment to defeat Raymond. This kind of setting that does not talk about martial arts is also based on history, and in the era of Huang Feihong from 1878 to 1880 (Master Huang was 22 years old when the Kelly Gang was wanted by heavy money), Australia gave birth to the Kelly Gang, which is famous for its plate armor. The most iconic piece of equipment of the Kelly Gang is their rough armor made of iron ploughs, and the bandits who graduated from the prenatal education have not found any reliable information on knight plate armor, and their inspiration is the ancient Chinese armor costume worn by the Chinese in Beechworth (Australia's famous gold rush town) during the festival parade. Although Kelly's prototype for armor was unreliable, they created dozens of kilograms of heavy plate armor, of which Kelly himself wore the one that weighed 41.4 kilograms (91 pounds), almost half of his own weight. As set in the Western, the Kelly Gang Four abandoned the revolver and fired with a Winchester burst rifle.
With these four sets of ugly plate armor, the Kelly Gang began to let themselves go, shooting and killing three police officers in one go, and openly mocking the Australian police, becoming the public enemy of The Australian White Road. In the final battle of 1860, the Australians fired more than 15,000 rounds at them, but it was thanks to the protection of the plate armor that the Henry Martini rifle shot by the Australian strip did not headshot them. Eventually, the Australian police set them on fire and hit them in the leg in the smoke, which captured them alive.
Armor not only plays a role in police gun battles, but also plays a tenacious role in formal combat. In 1798, Napoleon's cavalry encountered the Mamluk cavalry, an old cavalry force, which was still armed with armor and had personal martial arts superior to Napoleon's cavalry in close combat. Napoleon's cavalry sadly found that their opponents were better at slashing than themselves, and their attacks were ineffective against the Mamluk cavalry, "the sabre slash had no effect on the iron-clad Mamluks", and napoleonic cavalry actually defeated their Egyptian counterparts in multi-service combat. The fighting in Egypt also stimulated the French cavalry, which stubbornly retained the cuirassiers. Due to the influence of the French cavalry, Prussia, Russia and other countries also maintained cuirassier cavalry wearing armor.
In the era when Engels and Marx concluded that firearms would eliminate armor, France still maintained 12 regiments of heavy cavalry (of which 10 were cuirassiers), Britain had 3 cuirassier regiments, Prussia also preserved 10 cuirassier regiments, Russia also had a huge organization of 3 cuirassier cavalry divisions (that is, 12 regiments), and in Europe in the second half of the 19th century, there were few corsochet regiments with armor in the army, and no one was embarrassed to call themselves military powers. European cuirassiers were used until the first world war, and at the outbreak of the first world war, the French cuirassiers, who had adhered to the Napoleonic War creed, bravely rushed to the German positions of machine guns and barbed wire.
The experience of The European military powers was also transmitted to Japan, and the politicians of the Meiji Restoration era in Japan had the experience of wearing lock armor for self-defense, and naturally accepted this concept and equipment, and the Japanese garrison stationed in northeast China also wore improved plate armor. It was not until the end of World War I that countries eliminated armor with new body armor.
