Given the timeline is there going to be Machine guns?

These would be an additional asset to have next to Field guns and Artillery that have a place within the games timeline.

the first most notable would be the Gatling gun. It entered service and prominence in 1862 first seeing usage in the American Civil war but also thew weapon was exported and used by various European Empires used in colonial wars

Later down the line for a later period of this mods timeline the Maxim gun would fit. Entered service in 1886., and saw use in colonial wars of the 1890s, and adopted by various nations. It was the precuror to the modern machine gun as the some of the machine gun designs of the 1900s that saw use in ww1 were directly descended from its foudations.
