Giant Orc

Very powerfull attack unit on of the best ingame

Note: while unit is very powerfull, upkeep in culture means that you wont have much of them, and probably it is better to not research them (to train them you'll need high level science) and focus on other areas

Note 2: if you're hobbit try to buy this unit, upkeep in culture in nothing to hobbits and the unit itself is powerfull
