In an effort to save the “Hummer” from being replaced by the JLTV, AM General debuted the reliability enhancement package. The vehicle includes underbody armor, rocker armor, lower windscreen deflector armor and energy absorbing seats as standard. With the B3 option, the vehicle adds perimeter armor, overhead armor, a rear ballistic bulkhead, optional side and door perimeter protection, front cowl and wheel well protection, and a single movement combat lock (SMCL). The weight with all this protection climbs to 12,100 pounds. It maintains the 6.5L V8 turbocharged diesel with 190-hp, and a max speed of 70 mph. The version on display at AUSA also featured efficient LED headlights, a step to the doors, a tool mount on the hood, an ammo tray on the roof, and M249 machine gun mounts at the rear doors.
