How important to the military development of Germany Italy and Russia was Spanish Civil War?

The Spanish Civil War gave the German military a chance to test new weapons and tactics in combat. The war gave the Germans experience in air warfare, tank warfare, and urban warfare. The Germans also gained experience in operating in a foreign country with different terrain and weather conditions.

Of particular importance was the development and testing of the Blitzkrieg strategy, which proved essential to the success of the German military during World War II. The Spanish Civil War also allowed the Germans to train and test their troops in combined arms operations, while allowing them to test their new weapons and tactics, such as the Junkers Ju 87 Stuka dive bomber and the Panzerkampfwagen III and IV tanks.

The Italians sent troops to Spain, and they fought on the side of the Nationalists. The Italians also provided the Nationalists with air support and military supplies. The Italian experience in the Spanish Civil War helped them prepare for World War II.

Russia

The Spanish Civil War gave the Russians a chance to gain combat experience and test new weapons and tactics. The Russians sent troops to Spain, and they fought on the side of the Republicans. The Russians also provided the Republicans with military supplies and technical assistance. The Russian experience in the Spanish Civil War helped them prepare for World War II.

In addition, the Spanish Civil War also provided the Soviet Union with an opportunity to test new weapons and tactics, such as the T-26 tank and the Yakovlev Yak-1 fighter aircraft. The experience gained in Spain proved invaluable for the Soviet Red Army in its defence against the German invasion in June 1941.

Furthermore, the Spanish Civil War also strengthened the military ties between the Soviet Union and other states, such as France and Mexico, which provided valuable support to the Republican cause. This helped lay the foundation for the broader international alignments that would emerge during World War II.

Overall, the Spanish Civil War proved to be a valuable proving ground for the Soviet military and played an important role in shaping the Soviet military's response to the challenges it would face in the coming world war.
