Since missiles, unlike rockets, are guided, they represent a major increase in warfighting capacity. While unguided rockets are terror weapons aimed at large civilian areas to inflict fear, missiles can be targeted towards specific infrastructure or locations. Analysts say that in a war, Hezbollah would likely use their missiles to target Israeli military targets, critical infrastructure, and air ports. Hezbollah had no guided missiles during the 2006 war. Hezbollah has reportedly used ballistic missiles in combat in Yemen against Saudi Arabia, which has allowed them to improve and test the missiles' payload and guidance systems.
