General info

As a licensed version of the British 105 mm L7 gun in the German tech tree, the 105 mm weapon carries the same rounds as the Leopard I and A1A1 with the DM13, DM12, DM23, and DM502, as well as the DM33 round from the Radkampfwagen 90 or M48 Super. However, the FMK.4 can also fire the American M416 smoke round, something the German L7A3 guns cannot do in-game, as well as its own unique DM63 APFSDS round.
