-    <Rollover>Probably one of the most primitive units in the game. Fighting with a sharp object at the end of the pole didn't require a lot of technology to develop. It also allowed the human to distance themselves from their attacker. As time passed the spears got longer and longer. Started with a fighting style similar to using a quarterstaff, then to using them in numbers as a 'pin cushion' vs. humans (sarissa in a phalanx). Later it was developed to combat cavalry. During the medieval period it evolved to the pike. These units tended to be armoured as heavily as possible.</Rollover>

-    <Rollover>Weapon is basically a developed sickle. Probably from the club, to the axe, to the sickle to the sword. It was the Romans who used them to combat the long range of the sarissa. Their spears were so long they had to use two hands to wield them. In a formation they were almost impossible to maneouvre. If flanked, they were easily cut down by a sword as demonstrated by the Romans at the battle of Cynoscephalae. Generally swordsmen were well armoured, had shields, and tended to be nobles. A good sword was an expensive weapon.</Rollover>

-    <Rollover>These were the skirmishers. These lightly armoured units would advance quickly, throw a hail of javelins and then retreat back to their ranks. Grab another spear and repeat. They would do well against any unit that wasn't wearing proper armour, but more poorly if they fought hand to hand vs a well armoured unit. They didn't always have to throw their spears either. They used these light small spears in hand to hand similar to a quarterstaff. Also note that the development of the pilum was a key transition. The pilum was a weapon with a long steel shaft that would sink into a shield and was nearly impossible to remove. This rendered the shield useless. They also weighted and balanced them to make them accurately hit with a punch.</Rollover>
