Did the hittite soldiers use the alphabet in their battles to capture babylon

The answer is false. The Hittites used their chariots to capture Babylon. They dominated the Old Babylonian Empire in 1595 BCE. The empire had been disintegrating in the years leading up to the Hittite attack which was more like a sequence of destructive attacks instead of a campaign intended to gain territories. When the Hittites attacked, capturing Babylon and other cities, they did not join all of the Babylonian Empire and they only implemented power over Upper Mesopotamia.
