Tactics of the Roman Legionarre
The ranks could be several men deep, allowing a fresh man to be rotated to the front when needed so as not to break the formation. This tight wall of men was protected by the large scutum (shield) and it was common for battle to be engaged by raining pilums (spears, 600008) down on their foes. This throwing spear purposefully had a very small head on a long iron shaft that would embed itself in its target and then bend, dragging down with it the impaled target, which was often the opponents shield. This thin iron shaft bending held another benefit - your opponent couldn’t throw it back at you!
