Assessment of Hezbollah's indirect fires ability varies. Some studies say that indirect fire is a Hezbollah weakness, while others say that Hezbollah's indirect fires deserve "high marks" and the LA Times claims that Hezbollah has "well-trained artillerymen." The party's fire discipline is reportedly much better than that of Palestinian groups. A US Army publication explains this disagreement by saying that although some indirect fire support components like mortar marksmanship were strong, Hezbollah was rarely able to mass indirect fire, and overall Hezbollah was "far short of contemporary Western standards." Iran has transferred to Hezbollah some old artillery fire-control, targeting, and damage assessment systems. Hezbollah artillery participated in the battle of Salma, the battle of Zabadani, and the Battle of al-Qusayr along with other groups' artillery.
