Sub Base is one of two Arctic-based maps on Call of Duty: Modern Warfare 2 (the other being Derail). It is a medium sized map featuring a submarine base and two large buildings, both of which have accesible rooftops. Due to it's abundance of medium and short sight lines, it is a favourite map for users of assault rifles and SMGs.
