Have you ever thought about how different the Americans and Romans are? They have different lifestyles, cultures, traditions, and their military is different too. Even though they are different, they are also the same. Their military is different and the same because of the way they train soldiers, their ranks, and their uniforms.
Roman soldier’s armor is either made out of metal or leather. They will carry around shields for protection and fight with swords or any other weapon a craftsman made for them. American soldiers are different, instead of metal and leather they would wear camouflage to blend in and instead of swords and shields they will carry guns and haul cannons with them.
