WARRIOR Variants - Operations - Upgrades As early as 1967 the first proposals for a concept of requirements for a new armoured infantry fighting vehicle were collected in the United Kingdom. The late 1970s saw the concept taking shape under the designation MCV-80 (Mechanised Combat Vehicle for the 80s) and in 1985 the vehicle was given its official name "Warrior". Since 1987 the Warrior serves as the backbone of British armoured infantry units.
