Description
The GUN Military Truck resembles a colossal Mack Superliner and/or GMC General, being as wide as a two-way street and as tall as a small building. 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. on the sides. In Sonic Generations, the GUN Military Truck was given a slight update in design, possessing more refined details and armor, but otherwise remained much the same.

The GUN Military Truck is quite a powerful and durable vehicle, capable of running over cars and entire apartments buildings without slowing down. It is also very fast despite its size, being able to keep up with Sonic's running speed and can make extremely sharp hairpin turns at top speed. In Sonic Generations, it shown to possess additional features, such as three massive circular saws on controllable arms protruding from the top of its cab, rocket boosters that allow it to fly and can release various robots deployed by G.U.N.

Sonic Adventure 2
The GUN Military Truck's debut appearance was in Sonic Adventure 2 and later its remake, Sonic Adventure 2: Battle. It can only be encountered in City Escape. Here, it was send to recapture Sonic after he escaped from the military's custody.

The GUN Military Truck will appear behind Sonic after passing the last Point Marker in City Escape. From there, the GUN Military Truck will chase Sonic down through a section of the Stage where the camera angle has been turned 180 degrees. During the chase, the truck will slow if Sonic slows down too, though it will not stop pursuing him. Touching the GUN Military Truck will damage the player, and the truck itself in indestructible, meaning the player has to keep avoiding it until they reach the end of the chase where the GUN Military Truck will crash into a brick overpass. In Hard Mode for City Escape, the GUN Military Truck will faster and less forgiving.

Sonic Generations
The GUN Military Truck made a reappearance in the console/PC version of Sonic Generations as a part of the remade version of City Escape. It appears in both Act 1 and Act 2 of the Stage where it serves as an obstacle to the player. Like in Sonic Adventure 2, the truck is indestructible and will damage the player

Act 1
In City Escape Act 1, the GUN Military Truck continues its role of perusing Sonic, but does so from two different angles. Here, it can either pursue the player through different sections or move towards the player from somewhere in the background at certain points in the Act where it can both damage the player and destroy platforms, thus eliminating nearby shortcuts the player can take. This can be avoided if the player uses the platforms before the truck destroys them. At the end of the Act, the GUN Military Truck will pursue Sonic again only to crashes into a bridge support beam at the Goal Plate.

Act 2
In City Escape Act 2, the GUN Military Truck is encountered in the way as it was in Sonic Adventure 2. Like in Sonic Adventure 2, the player encounters it near the end of the Act and has to outrun it, with the camera angle having been turned 180 degrees during the chase. However, in addition to pursuing Sonic, the GUN Military Truck will also use three sawblades attached on its cab to attack from afar, which the player can avoid by moving to the side. Near the end of the chasing section, it will use its rocket boosters to chase after Sonic on a vertical wall. It is ultimately defeated after it crashes into a large building, causing it to explode.

The GUN Military Truck makes a small appearance in the Sonic the Hedgehog comic series and its spin-off comic series published by Archie Comics as a part of the comics' adaption of Sonic Adventure 2. It has so far only appeared in Sonic the Hedgehog #98, where Sonic ran into the GUN Military Truck and had to flee from it after escaping from Paladin Team Sigma-Alpha 2.
