Normally one concentrates the artillery barrage with the tank-infantry assault in space and time.
A series of short sharp attacks delivered at different locations would nibble up the Hezbollah operating space.
The Hezbollah would be forced to counterattack, which brings them out of their holes.
The problem: what do the Israelis do with the women and children that are captured by the offensives? Of course Israel doesn't make war on women and children, and would load them onto busses and evacuate them, thus inflaming the "Arab Street" which would murder Jewish women and children out of hand. Of course Hezbollah would try to ambush the busses on their way out of the combat zone.
There is nothing like taking ground to convince an enemy that he has lost. Nothing like shooting him down by thousands as he counterattacks to reduce the population of his fighters.
