Do they have any ordnance of significance that they haven't yet used that could make their "charge" more likely to succeed? I'm thinking MOAB...
They've been having problems because Hezbollah is so well dug-in to the terrian...its hard for artillery and air strikes to target them. Look for a heavy armored spearhead through the center of the Hezbollah fortifications, maybe accompanied by airborne movements, with the goal to encircle and flank the Hezbollah positions.
