Jenkins' Jetter is his owned modified Marauder Jetter. He altered the Jetter making it a vehicle capable of destroying EDF bases singlehandedly. At first he greatly improved its armor and weight so it has a steady grip on the ground. He did of course lose speed, but this isn't too bad.
Next to that he removed the big bulk on the back and added a platform with both a Heavy Machine Gun and a Rocket Turret. Finally he added a shovel blade with the text; "EDF GO HOME!" The jetter is also next to indestructible and can be used in Jenkins "side missions" which are located around tharsis
