False. Sturmgewehr was first to be designed and fielded in battle. The two rifles that developed from the sturmgewehr were the cetme and the ak-47. It had a lot to do with where the engineers, Schmeiser (sp?) and Vorgrimmler (sp?) ended up post-war.The AK-47 was revolutionary because it was the first weapon to combine the portability of machine pistols that had proved popular in World War II with the accuracy of less portable, sharpshooting weapons and the firepower of the heavier, more traditional machine guns.
