The M56 Howitzer is a Yugoslav-made 105mm artillery gun that is based on the American M101 (m2A1).


The origin design was heavily copied from the M101, with some technical improvements to increase its capacity. It was originally manufactured in Yugoslavia in a 28 caliber version that had the capability to reach up to 13 km. Through the years, it was modernized to have a 33 caliber with a stronger breechblock and new recoil systems that allow it to fire modern rounds up to 18+ km, as it was able to handle higher pressure in the chamber and had a longer barrel. It was initially marketed by Yugoimport, but is now manufactured and sold by BNT TMiH in Bosnia.[1]

According to the United Nations, some 1,500 units of the M56, in its various models, have been produced and over 200 were exported between 1998 and 2004.[2]
