How big was the weapon gap between Russia, Britain, France and Turkey during the Crimean War?

In fact, you have answered eight questions backwards. Relatively speaking, the teacher's expedition was to Russia. 1. During the Crimean War, Russia just annexed Crimea. Fighting here, Russia doesn't have the advantage of "home" at all, and everything has to be shipped from distant hometown. And his opponent, Turkey, has the advantage of local operations. At that time, there was no railway, and the convenience of land transportation was far less than that of sea. In other words, the Russian army has to go far away, and Britain and France have logistical advantages by boat. 3. In terms of military technology, the British and French armies already have the rudiment of a modern army, including not only weapons, but also training tactics and so on. The Russian army is still dominated by serfs, and its cultural quality is low. It is impossible to master the skills that the army needs now. This gap is all-round. 4. Because Crimea is a peninsula in topography, the navy occupies a large proportion in the victory or defeat of the war. Britain and France are maritime hegemons, Russia is a land power, and the terrain also limits Russia's play. 5. Finally, talk about technology. In the Crimean War, the British and French fleets took the lead in adopting steamboat armored ships, which was a revolution in naval technology. To sum up, it is not surprising that Russia is not superior in time, place and people, and its technology is backward.
