[Ansteorra-archery] What are things that are keeping out CombatArchers of the field?

>As long as they are on the other side. Don't forget the opposing archers
and
siege crews, they are fair game as long as they don't have red pheons on
their helms.

okay , so now I'm confused ??  I thought combat archers had to wear red
peons ??
and non combatants had to wear white diamonds ??
