Ok, some stuff with Fortify. In Civ 4 you slowly get 5% Fortify per turn right (max 25%)? If you Fortify this turn and then hit End Turn and the enemy attacks you next turn does your unit get 5% defense?
If you moved your unit last turn but didn't move your unit at all this turn, when you hit end turn and your enemy has his turn, your unit will have 5% fortify bonus.
