Question: On what dates did the war start and finish where M48s were used with mixed results? Passage:M48s were also used with mixed results during the Six-Day War of 1967. On the Sinai battlefront, Israeli M48s upgunned with the then-advanced 105mm L7 rifled tank gun were used with considerable success against Egyptian IS-3s, T-54s/T-55s, T-34/85s and SU-100s supplied by the Soviet Union during the 1950s and the 1960s (such as during the Second Battle of Abu-Ageila. However, on the West Bank war-front, Jordanian M48s (Jordan was also a user of the M48 Patton as was Israel at the same time-period) were often defeated by Israeli 105mm-armed Centurions and WWII-era upgraded M4 Shermans (M-51s upgunned with French-built 105mm tank guns (not to be confused with the British L7 105mm tank gun)). In purely-technical terms, the Pattons were far superior to the much-older Shermans, with shots at more than 1,000 meters simply glancing off the M48's armor. However, the 105mm main gun of the Israeli Shermans fired a HEAT round designed to defeat the Soviet T-62 tank, which was the USSR's response to the M48's successor in US service, the M60 Patton. The Jordanian Pattons' general failure on the West Bank could also be attributed to excellent Israeli air superiority. The Israeli Army captured about 100 Jordanian M48 and M48A1 tanks and pressed them into service in their own units after the war, as the same as were the Jordanian M113 APCs they seized during the war.
