The army also had special technical units. They accompanied the army and had chariots for the battle field and wagons for transporting necessary equipment which would include not only the obvious items of rations and tents but also such specialists types of equipment such as siege engines and rams (Saggs, 244). When roads had to be cut, a task force of men equipped with bronze, iron or copper picks and axes would hack a path for the army to pass through. Not even a river could stop the well-equipped Assyrians. If the river could not be crossed on foot, they would construct boats or bridges to cross the river with. The bridges were most commonly boat bridges, bridges formed by tying a number of boats together across the river with planks on top to make a footway or even a road for the chariots to pass over (Saggs, 244). Other specialists in lesser numbers included scribes for recording booty and other details of the armies campaign (Sags, 244).
