Missile Silos are not very common in the game, but when they do appear, are often used as mission objectives. The only mission in the main game they are used though is in the "Showdown at Big Honshu" in BWII where the Solar Empire needs to destroy the Anglo Isles' Missile Silos to prevent their fleet from being totally destroyed, thus giving the Anglo Isles total control of Solar Empire waters. The Anglo Isles is the only known nation to have these in the main game, Although in one of the Wifi Assualt missions, the Xylvanians are required to destroy two Frontier Missile Silos as well as a radar installation in order to carry on to the next objective.
