Is it possible that when Parson referred to the Battle Bears, he was just just referring to the Cloth Golems? On page 49, he is seen ordering a dragon stack (where Leeroy Jenkins can be seen atop a red dragon) against an RCC group "I want the battle bears...", But on page 50 that same group is seen destroying cloth golems.
 Siege engines?
It seems to be that we shouldn't talk about siege engines but about siege units. "Siege engine" should redirect to a page called "siege units," which would contain this page's current contents.
