 A variety of ammunition has been developed for use by tanks with guns based on Rheinmetall 's original L / 44 design . This includes a series of kinetic energy penetrators , such as the American M829 series , and chemical energy anti @-@ tank warheads . Recent ammunition includes a wide range of new anti @-@ personnel rounds and demolition munitions , giving tanks armed with the L / 44 and its derivatives greater versatility on the modern battlefield . The LAHAT , developed in Israel , is a gun @-@ launched missile which has received interest from Germany and other Leopard 2 users , and is designed to defeat both land armour and combat helicopters . The Israelis also introduced a new anti @-@ personnel munition which limits collateral damage by controlling the fragmentation of the projectile .
