"The Mg15 was initially designed by Theodor Bergmann ( the mind behind the MP18) and Louis Schmeisser in 1910. The MG15na was introduced in 1915, with several modifications on the original (na represent ‘new model’) it was an important weapon in the German arsenal. In being lighter than the MG08/15, and offering a similar rate of fire, the weapon also filled the gap between the category of rifle and hmg. The MG itself saw use in most theaters of the war, with a many being issued to the German ‘Asia Korps’. It saw a large order placed by the German army after the battles of 1916, as the German army needed something light that could combat the Lewis gun - the closest being German captured Madsen guns.
In game the MG15na will boast a very similar rate of fire and general usage to that of the MG08/18 variants. The MG15na offers alternate iron sights, which offer a little more vision than the MG08/15. The MG15na will be used by specialist german squads."
