 The Israeli Army introduced a new round known as the Laser Homing Anti @-@ Tank ( LAHAT ) projectile . Using a semi @-@ active laser homing guidance method , the LAHAT can be guided by the tank 's crew or by teams on the ground , while the missile 's trajectory can be selected to either attack from the top ( to defeat enemy armor ) or direct attack ( to engage enemy helicopters ) . Furthermore , the missile can be fired by both 105 @-@ millimeter ( 4 @.@ 1 in ) and 120 mm tank guns . The LAHAT has been offered as an option for the Leopard 2 , and has been marketed by both Israel Military Industries and Rheinmetall to Leopard 2 users . Israeli Merkavas make use of a round known as the APAM , which is an anti @-@ personnel munition designed to release fragmentation at controlled intervals to limit the extent of damage . Fragments are shaped to have enough kinetic energy to penetrate body armor .
