The Gouf was developed for ground combat, but once it was deployed on the front lines, issues regarding its operational utility in real combat began to surface. This modified Gouf Custom retained the melee combat abilities of the Gouf but also added improvements to its mid-range combat performance, making it a highly balanced machine. Since only a handful were manufactured, they were extremely hard to come by. Some machines adopted detachable optional equipment and regained their general type characteristic by utilizing frontline modifications. This machine was one of the frontline variations, and was also the personal machine of Lieutenant JG Visch Donahue of the Australian occupation force, also known as the "Thunderbolt of the Wilderness." Its modifications included the replacement of its left arm and heat rod with conventional portable weapons.
