Sorry for typo, battlegrounds of 2-3 infantry units. 1 spear accompanied by 1-2 billmen. The spear usually take minimal damage, but also cause minimal damage, it's the billmen who usually do most of the damage.

And as for the crossbow-ghulam bodyguard thing I mentionned, you should believe me on that. I offed about 2767+ enemy units and I was probably less than 1000. Light cav turns the tide more often than my heavy cav for me. Even if it isn't particularly realistic.
