2. The essence of World War II is the battle of big countries, and small countries depend on big countries for existence. So although Germany killed Europe, in fact Germany only defeated a big country, that is, France. Before Germany attacked France, it had signed a peace treaty with another European power, the Soviet Union, which carved up eastern European countries such as Poland, and the Soviet Union invaded Finland. So Britain fought Germany alone in Europe. Obviously, the British delivery is far away, and the German delivery is near, so in Europe, Germany's combat power is obviously stronger than that of the British.
3. In North Africa, the distance between the two countries is almost the same, while the British maritime power is stronger, so Germany is not dominant.
The Soviet Union carried out a large-scale counter-revolutionary movement in 1930s, and a large number of experienced officers were killed by Stalin, which greatly weakened the Soviet Union's combat effectiveness. This was clearly reflected when the Soviet Union invaded Finland. The Soviet Union was beaten out of the water by tens of thousands of Finnish troops, relying on the advantages of the Soviet Union to fight a war of attrition before defeating Finland. The tactical quality of the Soviet Union was very low at that time, which is why the Germans were able to quickly defeat the Soviet Union at first, but with the increase of the German delivery distance, the climate changed.
5. 1945, the Soviet Union has been relatively strong after several years of actual combat, but Japan's national strength is different, and it is getting weaker and weaker under the air and sea attack of the United States. When the United States dropped the atomic bomb, Japan's morale plummeted and its military industry collapsed. In this case, it is not surprising that the Soviet Union that attacked the mainland defeated the Kwantung Army that fought in China.
6. Britain spans the whole continent and has no advantage in competing with Japan in Asia. What's more, at that time, Britain's national strength could only deal with the ability of one Germany.
7. In fact, the combat effectiveness of the US military is the strongest. Because there are no powerful countries around the United States, the United States has not developed an army and an air force, only a navy. After the attack on Pearl Harbor, the US Navy took the initiative in Japan in less than half a year. Similarly, due to the needs of the war, the United States has vigorously developed the army and air force, gradually maturing from the initial rookie, showing strong attack capability, strong firepower and air strike capability. Therefore, the United States can win the battle across two oceans with a very low casualty rate. During the whole World War II, the number of American soldiers killed was always less than 300,000. It can be seen that the firepower intensity of the US military is super strong. The United States declared war at the end of 194 1, which was equivalent to 42 years of war. At the end of 1942, the Axis countries began to be passive.
8. Blitzkrieg is an advanced tactic, relying on tanks and planes. It was originally put forward by Fuller, an Englishman, and Germany took the lead in adopting this tactic. Therefore, all major countries in the world have the hardware foundation of blitzkrieg (tanks and planes). At the beginning of World War II, France was defeated by Germany because it didn't realize the superiority of this mode of warfare. Therefore, France lost in operational thinking, and other big countries will soon learn this tactic.
Summary:
In terms of soldiers' quality, Britain, the United States and Germany are at the same level. They are well-trained and rational, and solve difficult problems through new technologies and tactics.
In the Soviet Union and Japan, the Soviet army mainly focused on quantity and consumption, which is also the reason why the Soviet army suffered huge casualties every time. Although Japanese soldiers are the most tenacious and face death like martyrs, they lack rational thinking, and many of them are fearless sacrifices, which cannot be solved from weapons and equipment.
The Italian army is indeed the worst big country.
In short, in World War II, the US military gained the firepower advantage of the US military in any place and in any environment by relying on its strong national strength, powerful air power, ground tanks, intensive firepower and super naval power, and has already demonstrated the power of a superpower.
The Soviet army has a quantitative advantage, which can offset the quality advantage of the other side. Relying on the advantages of geopolitical powers, it has strong offensive and defensive capabilities.
Britain and Germany are evenly matched, and relying on naval power gives Britain an advantage when facing the Germans outside Europe. Germany is dominant in continental Europe. Only America can beat Japan in Asia.
