A military classic, ANK MK38 flipped in the middle of a trip.

The ANK MK38 is primarily based on the AM General M939. It is nearly identical with slight modifications to the grille and turn signal design.
The MK38 is a juggernaut offroad. Even without engine and gearbox upgrades, it is among the fastest offroad trucks in the game, due in no small part to its Always On AWD and Diff Lock. It also possesses an impressive power-to-weight ratio allowing it to move loads without any major loss of speed, sometimes even including an attached trailer. With upgrades, it is nearly unstoppable and will tear through any kind of terrain at an impressive rate. Its default tires also have excellent mud ratings which give the vehicle lots of traction. It can be equipped with AMHS Mud Tires to further improve its performance as of Phase 2, as well as Tuned Custom Suspension for increased ground clearance if stability isn't a concern.
Its good performance however is offset by its monstrous fuel consumption and poor stability, both of which hamper its speed advantage greatly. While mud tires can deal with the latter and give the vehicle extra grip, their short operating range is a huge problem. Its other weakness lies in its total lack of frame add-ons, restricting it to more of a cargo hauler than anything else.
