The rockets used against Israel are fired from trucks who purposely do it from the shelter of Mosques, Hospitals, Appartment buildings and schools. When the plot indicates a target the Israelis fire back or do an air attack and of course the truck is gone and the casualties are classed as non combatants. Rather like the RPG's and snipers, who surround themselves with women and children in the hope the israelis will not shoot back, or that when they do the collateral damage can then be used against them in the international press.
