i so far thought protection helps against missile attacks .

The protection from all sources is used against missiles. This includes that from shields.

A unit's defense does not matter when being attacked by an arrow. The attack roll on the projectile is 10+2d6, while the victim's roll is 10+shield defense modifier+2d6. A tower shield for example has a defense modifier of 4.

This is referring to the chance to actually hit the target when the missile lands in its square. The unit's defense from armour and combat ability don't matter, but the defense from shields does.
