Well the link Jack provided stated:
“Merkava 4 main battle tank capabilities
The tank is capable of carrying eight infantry soldiers, a command group or three litter patients (stretcher casualties) in addition to the tank crew of commander, loader, gunner and driver. The tank is capable of firing on the move at moving targets and has demonstrated high hit probability in firing against attack helicopters using conventional anti-tank munitions.
Major contractors include: the El Op Electro-Optic Industries subsidiary of Elbit Systems which is responsible for the fire control system; the Israel Defence Force which carries out main construction and system integration and testing; Israel Military Industries for the supply of the main gun, ballistic protection and munitions; Imco Industries for the electrical systems; Urdan Industries for the hull, main turret and castings; and IAI Ramta for protection components.
The main part of the tank production, the construction of the hull and integration of all the systems is carried out in the Israel Defence Force workshop.”
Just going by what I read. Can’t vouch for the veracity.
My daughter worked partially on this tank. It’s HEAT/infra red is incredible and yes it has a long range missile/shell that can slam a target miles away with some sort of electronics that keep it not only on course but with the same speed...I don’t know much at all about tanks and shells, she just told me the declassified newspaper version. her main skill is molecular bio, says it can discern human from animal and optices can discern children from adults but i guess most tanks do that now.
