Archer	Flier.	Spear.	You'll want to keep units between your archers and enemy forces, you see, they'll be massacred in direct combat -, however, as the name should apply, they're capabale of ranged attacks.
Bandit	-	All	Barbarians are crap. The actual Bandits arent too bad. Just really weak defense.
Flier	-	Archer	Fliers strikes from the heavens above, out of range of common swords and spears. They seem able against most opponents, an overall good force. Fliers always have a 25% tactical bonus, and can only kill equal to or less than their own number.
Gel	-	-	Gels are rare, and with their high defence and relatively high attack, that's probably good. I haven't found them weak or strong against anything particular - use what you got.
Holy	Evil/Undead	-	They’re good against undead and weak against everything else, would you expect anything else?
Horse	Soldier	Spear	Quick and powerful: Are the reasons I like cavalry units – they’ll maul your enemies, unless they’re armed with pikes or fly.
Sea	If in water: all.	If not in water: all	Good in water, bad outside – this is due to the defensive bonus given in water. Nixies are still good out of water.
Soldier	Spear	Horse	Soldiers are an overall good unit type, and are capable of most tasks - unless cavalry is included.
Spear	Horse & Archer.	Soldier	Pikes, shields and heavy armour: Spear units are good to block advancing enemy cavalry and resist archers' arrows.
