I always wondered, when people used snowballs in battles to damage the opposing forces armor, why not just roleplay the snowballs as rocks instead of actual snowballs? It makes much more sense considering rocks are harder and can potentially dent armor depending on how hard it's thrown and other added factors. Rocks are also plentiful on a plain I would imagine, or they could've been dragged in pouches by each soldier. It's a good tactic, too.
