Mutants, mutant soldiers and mutant sergeants are one of the main infantry troopers of the Forgotten. They assisted GDI against CABAL and Nod during the Firestorm Crisis. They can cut through infantry and most light vehicles, but have light armour. They are led by Mutant Sergeants. As with most of the Forgotten, the soldiers left on a self-imposed exile to unknown areas between the Second Tiberium War and the Third Tiberium War.
Despite having different sprites and entries in the Tiberian Sun rules.ini file, these units are identical in stats.
