|This material is published under the OGL| Horses are widely
domesticated for riding and as beasts of burden. A horse not
trained for war does not normally use its hooves to attack. Its
hoof attack is treated as a secondary attack and adds only half
the horse’s Strength bonus to damage. (These secondary attacks
are noted with an asterisk in the Attack and Full Attack entries
for the heavy horse and the light horse.) SEE WIKIPEDIA ENTRY:
