The New York Times reports that 20% of ATGM attacks on tanks caused casualties or penetrated armor, but Israeli military reports suggest this number was higher, at 45%. Hezbollah fought battles of maneuver and attacked fortified Israeli positions. Hezbollah's strategic maneuving capability is a main weakness, but the party's skills in tactical maneuvering are "proficient". Although the fighters were highly mobile within their areas of operation, strategically Hezbollah's defensive position was basically static. The IAF's overwhelming firepower and communication problems meant that retreating or attacking were rarely possible. Instead of retreating, Hezbollah members took off their uniforms and disappeared into the civilian population. Hezbollah conducted ambushes that separated Israeli infantry from armor units and inflicted more casualties per Arab fighter than any of Israel's previous opponents. However, ATGM teams had poor night-fighting capacity and were slow to regroup when retreating.
