 He's got a spear. The head of his spear weighs 15 pounds, and it's pure iron. Not only does he have a spear, but he's covered from head to toe in armor. He's got a shining helmet of bronze. He's covered in chain mail that weighs about 150 pounds. He's got his own shield-bearer. He doesn't carry his own shield. Some other poor guy carries his shield in front of him, a shield that would cover him from head to toe as well.
