Gun-howitzer

Gun-howitzer (also referred to as gun howitzer) is a type of artillery weapon that is intended to fulfill both the role of ordinary cannon or field gun, and that of a howitzer. It is thus able to convey both direct and indirect fire.

To be able to serve as a howitzer, gun-howitzers are typically built to achieve up to 60—70° of elevation. For effective direct fire, the gun-howitzers typically employ a fairly long barrel, usually not shorter than 30 calibres. Its ammunition also has a high muzzle velocity and often large calibre (often exceeding 120 mm).
