 Such a purchase was seen as part of a two-tier equipping strategy - the wheeled 105mm-armed ACV and some other lighter-weight equipment for OOTW and a main battle tank (MBT) and related heavier equipment for warfighting.However, by the mid-1990s elements of the Canadian army were envisioning the ACV replacing both the AVGP Cougar and Canada's obsolescent Leopard 1 MBTs as part of a move to a medium-weight wheeled army.In 2003, Canada announced that it would replace its Leopard 1s with lightweight Mobile Gun Systems.
