How did the art of war develop and what new types of weapons were invented by the Assyrians?

The ancient Assyrians were very skilled in military affairs. So they were the first to widely use cavalry in their troops. In addition, an important military innovation they had was the use of siege weapons, that is: rams, catapults, ballistae, siege towers, etc. They were the first to create siege troops, whose task was to storm the ancient fortresses. Thanks to such innovations, the Assyrians were able to conquer vast territories in the Ancient East.
