The stationary gun would allow robots to be used in other areas that required a more fluid movement and not be stuck guarding perimeter areas and blockades. Where the land mines and booby-traps provided a passive obstacle, the gun could target troops before they made it to the areas that they did not want them to be in. It also made their forces seem much larger and would occupy enemy forces away from more critical areas. The enemy would waist resources trying to take out the gun emplacement only to be drawn into a mine field or booby-trap zone of no real tactical significance.
While they were in the design for the small gun system, they decided the guns on the ships would be more effective if they could target multiple targets at the same time. With a little redesign and by moving some of the circuitry into the hull they were able to make each gun have three nodes. Which meant they could target three targets at the same time. They also decided that the Bashers needed side guns to make them more effective. They added two more guns to the sides of the larger ships as well, for a total of four on each side. Ship was fitted with the new gun design and they were able to add twenty to its hull. The gun systems were setup so they could fire the new smaller missiles and they did some calculations to determine the best distance away from the target to achieve the most kinetic force.
