The GUN Military Truck keeping up with Sonic's speed, from the console/ PC version of Sonic Generations. In Sonic Generations, the GUN Military Truck was given a slight update design-wise, possessing more refined details and armor, as well as an extra set of seats with its own windshield set just above the main one, but otherwise remained much the same. It is predominantly grey and black with a heavily armored exterior, has the 'GUN' emblem written on the front and possesses an equally large semi-trailer with the symbol of G.U.N.
The GUN Military Truck resembles a colossal Mack Superliner or GMC General, being as wide as a two-way street and as tall as a small building.
