Although the HMMWV has been in production since 1985, its design is still as revolutionary today as it was when engineers began initial concepts in 1979. The final design met military requirements to replace numerous types of aged vehicles and to keep up with swift moving tanks. The Army wanted durability, mobility and reliability. The unique geometry of the truck provides these qualities. No other light tactical vehicle in the world approaches the HMMWV's capabilities or cost effectiveness.
