S.C.U.M. Soldiers make-up the bulk of S.C.U.M.'s combat forces, and are considered elite troops. They are made-up of war veterans from before the Armageddon Wars, and S.C.U.M. Raiders who proved their worth. They have been trained in small force tactics, use of all known types of small-arms weapons, martial arts, demolition, electronic warfare, interrogation and psychological warfare, with additional training available for specialists. These men are also made utterly ruthless by their training, with an emphasis on social-Darwinism, and washouts do not live to have another chance - they usually have a high drop-out rate. Discipline is enforced through fear, as punishment for even minor offensives is harsh. They follow the orders of Skull Hawk, but their loyalties lies with Cyclops.

They are a formidable force for S.T.O.P., as they are well-armed, highly skilled, and well organized. Fortunately for S.T.O.P., S.C.U.M. Soldiers are not as elite as their reputation would precede them, and they are often thwarted by the advanced skills and tactics possessed by the members of S.T.O.P.
