Iranian military theorists downplay the impact of advanced weaponry for Hezbollah, suggesting that human resources are more important for determining victory. Some independent analysts concur, suggesting that the group's skills, tactics, and organization are more important than the weaponry it possesses. Hezbollah's weaponry is only one component of their overall strength and should absolutely not be seen as indicative of their military strategy. Since 2006, Hezbollah's military procurement has focused on air defense systems and surface-to-surface rockets with increased range and accuracy. Hezbollah is widely expected to attempt to acquire a precision-strike capability in the future. In August 2019, Israeli drones reportedly destroyed a factory in Beirut responsible for developing long-range precision missiles for Hezbollah. The party is also attempting to develop capabilities and operational concepts to attack American forces "in areas where they have traditionally found sanctuary."
