Apes are rather gentle creatures in the wild. What if you got a hybrid but it didn't want to fight?
Well, a Bonobo-Human would rape the enemy, considering that Bonobos have sex all the time with everyone.
Chimpanzee-Humans would go ape, pun completely intended, as long as they saw the enemy as a threat to its social position and its females, however, they may also see their own army as a threat, so, that's probably not such a good idea.
