Fiendish nests manned by Forgotten Mutants. It is similar, in every way of the normal Forgotten, except it does more damage and having no mobility. The Machine-gun Nest is a Forgotten immobile anti-infantry defensive structure which consists of a small team of infantry manning an anti-infantry machine gun turret in Tiberium Alliances. Even though it is immobile, it counts as infantry, so that means tanks can drive over them, and anti-infantry vehicles and aircraft are effective against them, even though the latter can be attacked.
