the literal reason israeli tanks got M2's on the main gun + machine guns for the commander and loader is to deal with enemy ATGM teams.

they found that lots of machinegun fire + smoke is how you deal with syrian ATGM attacks and later added lots of machineguns to all their tanks and it kinda stuck to this day. the M2 mounted on the main gun is there to use the main gun's super precise targeting system and recoil-absorbing large mass to basically do longe range sniping with the m2
