In some games, the amount of damage done to your units / you is damage – armour, while in others it can be more complex, such as damage – (damage* armour as a percent)
Where does Starcraft 1 stand on this?
If my unit now has +1 armour because I researched Zerg Carapace, is it a straight -1 damage, or some other calculation?
On a side note, what about the Protoss Shield upgrade, is that like a second armor, just applied to shields?

Each armor reduces the incoming damage by one, prior to any reductions. Then damage reductions are applied due to damage type and unit size. The minimum damage that can be done is 0.5 per attack.
