Zone of control (Civ2)

Zone of control (abbreviated ZoC/ZOC) is a game mechanic in Civilization II that restricts unit movement. Units located on land tiles exert a zone of control on adjacent tiles; foreign ground units cannot move within or between rival ZoC, unless the civilizations are members of an alliance. Zone of control acts to create and maintain a military front line, without requiring a "hard" wall of units occupying every traversible tile.

ZoC has several general exceptions: units moving onto or out of a transport, into or out of a city, or moving to stack with a friendly unit are not obstructed. Sea and air units are not subject to zone of control, though they will exert it.

Unit exceptions

Certain ground units are not subject to zone of control (but still exert it themselves):

•  Explorers and  Partisans;
• Espionage units ( Diplomats &   Spies);
• Trade units ( Caravans &  Freight).

ZoC immunity is a flag that can be assigned to any unit. The mechanic itself is hard-coded.
