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. However, the FMK.4 also can fire the American M416 smoke round, something the German L7A3 guns cannot do in-game.
