Half day isn't it champ? The names Centurion Mk.1, widely considered as the world's first main battle tank, or MBT for short. Im equipped with the QF 17pdr due to me being developed in 1945, maybe near the closing months of the war. Im mostly used during the 1950s to the 1960s by most Commonwealth nations, but the Jordanians still use me to this day through modernization. Oh, and I have a tea maker. As all modern British tanks would.
