Army Defence is an Army skill which can be learned at the university. This skill increases the defensive power of troops. At every level, transport speed is increased by 2%. The maximum boost at level 20 would be 40%. The boost can go up to 60% at level 30, although a level 30 university can only be built in a famous city.
