That's as inherently useless as an assessment based on pure numbers. The value of a troop can vary greatly by both technological level of game, and circumstance. The wrong kind of unit at the wrong time can be not only worthless, but even counterproductive. Does this mean that for every militia the player hires or acquires, his army strength goes down, as militias tend to do nothing but chew up upkeep while being difficult to get rid of?
