Faraz,
The M825 is actually a variant of the M151A2, it was used as a gun platform. A 105mm Recoilless Rifle was mounted on it, for use against Heavy Armor/Tanks. It is the same as the M151A2, just has a different rear and some different body fearures
Here is a picture how it should really look.

Ah yes the Patrol, its a mean machine! Exterior and Mechanically its perfect, but the interior and dash needs some work, otherwise it kicks ass.
