This is a Magach 3 tank, no. 818577, in which Yossi Regev, a company commander in the 421st Armored Brigade, fought in the Yom Kippur War. Regev's tank was the first to cross the Suez Canal on an amphibious tank-carrier on October 16, 1973.  Thanks to the Armored Brigades fighting on the southern front, the Egyptian 3rd Army was encircled and the Egyptian attack was warded off. At war's end, IDF forces were on the west bank of the Canal, 101 km away from the capital, Cairo.
