The Giant Missile Silo is a missile silo that appears in Advance Wars 2 and takes up a 4 by 4 grid. It appears in the Blue Moon mission T-Minus 15. After 15 days, it launches a giant missile that destroys half of Blue Moon's troops, resulting in a mission failure. To destroy the Giant Missile Silo, you must capture the surrounding 8 buildings, which will result in a victory. It also appears in the final mission of the campaign, Final Front. This time, you must destroy the Death Ray in front of the Giant Missile Silo to win the mission.
It also appears on certain maps in Advance Wars: Dual Strike, such as Dark City.
