Nevertheless, for many armies there was a divide between those in control of tanks and their doctrine, and those in control of anti-tank units and their doctrine. Since the first anti-tank guns were a form of towed artillery, it was the artillery branches which generally controlled these units, especially in Britain and Germany. The armored branches of these armies were still dominated by the influence of cavalry-based thinking, and were focused more on offense than the defensive need of anti-tank guns.
