Artillery/Heavy weapons for both sides, pom pom`s for example were used by both sides, another set of infantry for both sides would not be amiss, the British in slouch hats for example, far more common than sun helmets with both Brits and commonwealth troops as the war progressed. The Boers again could just be better, as infantry it was usually in a defensive roll and a second set could more accurately depict that.Transport, wagons and carts for both sides. Artillery limbers and crew, more uses than the Boer war, Afghanistan and the Sudan for example.
