Siegecraft is a technology in Age of Empires that is found in the Market during the Iron Age. This technology adds +3 stone gathering to Villagers, and also enables them to efficiently attack walls and towers by making them ignore building armor by doing up to 10 damage if Zealotry is also researched. This makes Villagers effective against towers in large numbers. This technology also improves both the range and attack of Slingers by 1 point.
Despite the written records and depictions of cities and fortifications being stormed with the aid of siege equipment, starvation was the only certain and effective way to take strongholds before the gunpowder age. The defender of a strong position, with adequate troops, food, and water, had all the advantages. Physical assault of strongholds was a difficult proposition accompanied regularly only by those armies posessing siegecraft- the necessary equipment, resolve, leadership, elan, discipline, and skill. Examples from ancient history were the army of Alexander the Great that conducted 20 sieges over a ten- year period, most after the fall of the Persian Empire; the Hittites, the Assyrians, and the Romans.
