Anti tank weapon scorecard
... Hizbollah fired some 500 ATGMs, and scored hits on about fifty Israeli armored vehicles. Not all the ATGMs were fired at armored vehicles, and about a third of them appeared to have been used against Israeli infantry....A little perspective on the effectiveness of Hezballah's favored tactic for stopping the Israeli offensive. It appears the Isaelis did a better job of stopping themselves than the Hezzies did in attacking their forces.
... The Israelis had over a thousand armored vehicles in Lebanon, and five percent of them were hit. It hurt, but the ATGMs did not stop the Israelis, or even slow them down much.
