 VM & VC 

During the First Indochina War, the French used to call their opponents ""VM"", ""Viet Minh"", short for the ""League for Indépendence of Viet Nam"" until the fall of Dien Bien Phu in 1954. Starting with the Ngo Dinh Diem Regime, it's been ""VC"" for the opponents until the Fall of Saigon in 1975. It may be usual to downgrade and demonize opponents.
