Juggernauts are decades-old assualt vehicles that have played a prominent role in military forces dating back to the days of the Old Republic. While the Juggernaut was considered state of the art when it was first developed, modern war vehicles, such as the AT-AT walkers have displaced it as the most powerful land combat vehicles in Imperial space.
    The vehicle was first built during the waning days of the Old Republic for use by the many planetary governments that had begun building their own defence forces. Juggernauts were sold to planetary governors, corporations, and even private interests, and quite a few fell into the hands of the Hutt crime clans (and a number of other shadowy group). Under Imperial rule, most Juggernauts were commandeered by the Army and proved to be particularly useful on outlying planets where Imperial commanders could not get AT-AT walkers.
    While Juggernauts use ancient technology, their sheer size and thick armor plating make them as though and dangerous as the AT-AT walkers. The Juggernaut is twenty-two meters long and nearly fifteen meters tall. Imperial troops have nicknamed the Juggernauts "rolling slabs" becuase of thier size and configuration.
    Five sets of drive wheels propel the Juggernaut to a top speed of two hundred kilometers per hour, although the primitive drive system requires the vehicle to slow to barely twenty-five kilometers per hour in order to turn. There are two drive stations, on at each end of the vehicle, so the Juggernaut can simply reverse direction. This is of great assistance in rough terrain and urban areas, where there is not enough room for the vehicle to turn around.
    Juggernauts can transport fifty troops into battle or carry speeder bikes, light assualt vehicles, and other small repulsorcraft. This cargo capacity matches or exceeds that of the Imperial AT-AT walker, although the Juggernauts terrain limitations and primitive drive system make the vehicle less attractive in the long run: a Juggernaut with a damaged drive system can spend weeks in repair bays while crews wait for replacement parts.
    Juggernauts require a crew of two, with an additional six gunners needed for the weapons systems. A single trooper in the observation tower provides targeting information to the gunners. The Juggernaut's weaponry includes a turret-mounted laser cannon and port and starboard laser cannons. These are as effective as the lasers on an AT-AT walker, although their older design limits their effective range to only two-thirds that of the walker's weapons. A medium blaster cannons is also turret-mounted and features both a longer range and better stopping power than do the chin mounted medium blasters on the AT-AT. Two concussion-grenade launchers are mounted on independent turrets, each draw on a magazine of ten grenades. They are used to lay down suppressing fire to protect troops exiting a Juggernaut.
