| Notes | The 40mm 40M was Hungary’s first real anti-tank gun. It was a combination of the 36M carriage combined with a barrel similar to that of the Bofors 40mm, and fired a similar round. The 40M was the standard Hungarian built light anti-tank gun during World War Two and issued in the same way as the 36M. |
