Cavalry Bases (20 x 50mm):
Warriors mounted on Horses (any kind)
Dire Wolves
Pit Hounds
(This is important as their large bases help balance their GC cost)

Heavy Infantry (25 x 25mm) OR Monster Bases (40 x 40 mm):
Ogre Bodyguard
Possessed
Rat Ogre
River Troll
Warriors mounted on Great Squig Mount
(Games Workshop uses 40 x 40 mm bases but we have found these to be too large. For an example of a monster on a 25 x 25 mm base see Asp’s Rat Ogre here.)

Infantry Bases (20 x 20mm):
Everything else
(Including Wardogs, Squigs, and Giant Rats)
