The new design was called Cougar to provide a degree of continuity with the older designs but had little in common with them. The former vehicles were almost entirely non-compliant with NATO standards for protection, human factors, and safety, which made those designs obsolete. The Cougar was effectively a totally new vehicle that incorporated the latest US-made automotives, a new hull design, and structure, as well as built-in growth potential, including dimensions that allowed for the addition of the latest armor and protection systems.
