The Specialised Infection Containment Operative was founded back in 2040, right during the start of the outbreak in the United States. Over the decades, their unit began to evolve and change. Adopting new equipment and combat techniques, they are quite capable to be deploy as regular infantry when need be, while also acting as security for M.S.E.F. SICO became heavily relied on during the start of the siege of 1W00XE and during the first and second battle of Osingard. However, they would also be divided into different branches, more knowable as the Specialised Anti Personnel Trooper (SAPT).
