Metal is necessary for warriors to become veterans. Fortify - increases the city fortification level. Fortification bolsters your defense against attackers. Train - recruits warriors from the local citizenry. If a captain is present, and a sufficient metal supply, training will also allow some warriors to become veterans.
Veterans are far superior in combat strength to warriors.
Ordain - initiates priests. Unspent labor points are lost. Each turn you should give orders to each one of your cities. Each order needs a destination. Priests, warriors, and veterans also require a strength selection which determines how many of the unit to include in the order.
