Maybe a cheat infantry unit could be added to the game in the future that uses the Nock gun. The cheat unit can have the name [Nock Gunner]. As one can tell from the picture shown below the Nock gun was a flintlock firearm with seven barrels and was used by the Royal Navy during the early stages of the Napoleonic Wars.
However, flaw designs of this firearm were quickly revealed as it was used in battle. The recoil caused by all of the seven barrels was powerful enough to injure the user or broke the shoulder of whoever was firing the gun. Due to the shortcomings of the Nock gun its service in the Royal Navy only lasted from (1782 - 1804).
