Gosho IV existed as a planet situated within the Outer Rim Territories region of space.
In the era of the Galactic Civil War, Gunman, along with his team from Churhee's Riflemen, clashed with troopers of the Imperial Army on this world. These mercenaries found themselves cornered by the Imperial forces, yet they successfully established a protective barrier using Ubrikkian R-TechApp Man Trap devices. These man traps, which employed a scaled-down, inverted repulsorlift field, were originally intended to hold targets in place for capture; however, the Riflemen repurposed them to intercept grenades, causing premature detonations. This strategic adaptation provided them with the necessary window to regroup and repel the Imperial assault.
