The Tiran 4 (רודן; lit. Tyrant) was a captured and slightly-modified Arabic T-54 in Israeli service. The IDF was well-known for receiving different types of tank both from military sales and capture of enemy vehicles; after Soviet Union supplied an abundance of T-54/55/62 series medium tanks to Arabic countries neighbouring Israel (i.e. Egypt, Syria, Lebanon) since the 1960s, Israel had the chance to capture hundreds of vehicles during the Six-Day War and Yom Kippur War, replenishing the heavy losses of the Israeli armoured corps, as well as using them to disguise as Arabic armoured corps to hit them unexpectedly. These captured Soviet-built tanks were named Tiran and the different numbers represented different types of tanks; in this case, Tiran 4 was the designation of modified T-54 with logistical modifications.
Introduced in Update "Danger Zone", the Tiran 4 provides the same firepower and mobility of a T-54 while still suffering from the same cramped interior space, a downgraded anti-aircraft machine gun (from DShK to M1919A4), unprotected ammo racks, and slow turret traverse speed. It's a good brawler and frontline tank, with access to a good APHE shell that can one-shot most enemies if you are able to penetrate the enemy tank. Its low profile and sloped armour make it very well protected against conventional projectiles.
