Many consider the OF-40 to be Italy's first attempt at making a main battle tank post-WW2. The OF-40 was made after experience gained from the OTO Melara Leone project, it being a modified Leopard I.

Introduced in Update 1.85 "Supersonic", the playstyle of the OF-40 is very similar to that of the Leopard 1 series of vehicles found in the German tech tree. The OF-40 does have slightly better turret armour, but the weakspots the Leopard 1 has pretty much are the exact same on the OF-40. Mobility-wise, the tank does not disappoint, the armament is also quite potent. The OF-40 is armed with a 105 mm cannon, although it is unstabilized which can be an issue when firing on the move, so it's best to fire whilst stationary. The vehicle also has access to a laser rangefinder, but it does not get access to thermals. Overall, this tank can be quite effective when a player can work around its weaknesses and make the most of its strengths.
