Peasants vs. Nobles

One team, the Peasants, starts out on a knee (but with all limbs intact, they just cannot walk or run) grouped in the center of the field.

The other team, the Nobles, start grouped on one side of the field or the other. Nobles are 'riding a horse' and so can walk / run until they take a leg shot which 'kills the horse' and then they drop to a knee (but their legs are both intact).

If a Noble is killed with out having a leg taken then their 'horse' can be taken, giving a peasant (or a Noble without a horse) the ability to walk / run.
