In 2006, Hezbollah's intelligence capacity and Iranian help gave them an "extraordinary understanding of Israel's military strategy", which was critical to successfully fighting the war. The party had "good tactical intelligence" and knew the IDF's commanders, likely routes of advance through Lebanon, and tactics. Hezbollahs' external intelligence service in 2006 concentrated on identifying "on targets and trajectory algorithm selection" for their rocket stockpile. Hezbollah's intelligence network in Israel remains heavily focused on identifying targets for rockets. Hezbollah's internal security apparatus is headquartered in Dahieh, Beirut. Hezbollah has influence within the government of Lebanon's security services. Since 2000, Hezbollah has focused on acquiring a database of Israeli civilian and military infrastructure via public reporting and spies to target with rocket artillery in the event of war.
