Move: the selected unit moves to a tile in his movement range.
Attack: the selected unit deals damaged to an enemy unit (and possibly gets damage dealt back) (more later)
Heal: the selected unit gets some of his health restored back (to a maximum of his maximum health) When in friendly territory, the unit heals 4 health back. When outside friendly territory, he restores 2 health.
When one unit attacks another one, he deals damage. How much damage is dealt, is dependent of the attacker's 'attack' stat, and the defender's 'defense' stat. If the defending unit isn't killed during the initial attack and he is in range, he deals damage back. The amount of damage is depended of the the defender's (Now attacker's) defense. If the attacking unit kills the defending unit and his range is equal to one, he moves to the defender's tile. If a unit ends his turn on a enemy's city, he will be able to capture this city on his next turn.
Damage dealt formulas:
Attacker: Damage dealt= 5+ attack*(health/10) - opponent_defense*(opponent_health/10)
<FILL IN PLEASE>
If a units kills 3 enemy units, he can be upgraded to a veteran. If a units gains veteran status, his maximum health will increase by 5, and he will be fully healed. This will take up an entire turn and must be taken as your first action.
