Do any units have both melee and missile attacks?
Yes, many units have both melee and missile attacks. Usually one is a primary attack and one is a secondary attack. For example, Archers fire arrows from a distance, but must resort to hand-to-hand combat if the enemy engages him close up. Archers aren’t well-suited for melee combat, however, so it’s wise to keep them at a distance. Samurai, on the other hand, prefer melee combat but is available in a supporting role as a missile unit.
