Squaddie

The Unknown Military ATV (unofficial name) is a military variant of the Mammoth Patriot that was cut from Grand Theft Auto V. It appears to be a modified variant of the Patriot, featuring a longer pickup-style body with a camouflage paintjob and various other performance and aesthetic enhancements that one would expect on a military vehicle. A picture of this vehicle can be seen on an advertisement for Warstock Cache and Carry, but it cannot be obtained at any point in the game, and there is no model for the vehicle inside the game's internal files.

Trivia

 * Given that it is an adaptation of the Patriot, it is assumed this is manufactured by Mammoth.
