Two units have been added to Isengard.
White Hand Stormers
Saruman's purpose is to dominate this Middle-Earth, though there can be only be one Lord of the Earth, and He does not share power. So Saruman has to outclass, outmatch and outwit one of the most powerful beings left in this world: Sauron. In his physical form, Sauron is neigh-invincible, but if one could strike at him from is blind side, he could beat him in the blindness wrought upon him in his desperate search to find the Ring. Saruman's Uruk-hai are not a mindless rabble of orcs: their armour is thick, their shield broad. This befits The White Wizard's mind of metal and wheels. Saruman will need the strength to storm the most powerful keeps effectively to launch a surprise attack upon Him that once supposedly was his overlord. With massive tower shields, the wicked hooked sword of Isengard and the plated armour of the furnaces of Orthanc, the White Hand Stormers are Saruman's hope to seize the initiative in the struggle for ultimate power and turn the tide in what seems a prematurely decided battle not for the Free Peoples, but for the power of Orthanc.
