The attack value of this unit.
An attack that is delivered via a diagonal gets one point penalty.
When more units attack an enemy unit in the same round the attack value of those units can be added together. The armour of the defending unit is subtracted first from every attack.
When the attack to another unit is higher than the calculated defence the unit is damaged. A damaged unit will fight with one point less attack and defence (mental and physical). A successful attack on a damaged unit destroys a unit.
When the remainder of the attack after subtracting the defence is higher than the normal defence score of this unit it is destroyed directly.
Then a unit is inside a friendly city for a turn the damage is repaired again.
