The P40 "G.C. Leoncello" is a gift Italian medium tank. It was introduced as a premium pack in Update 1.73 "Vive la France" and was removed from the store after 2020 May sale. It was made available briefly for purchase with Golden Eagles during the 2021 "Italian National Unity Day" mini-event.

The P40 "Leoncello" was one of the first Italian ground vehicles implemented and was created by Nicola "Kolin0" Faggiani and Riccardo "BlueBeta" Lo Verso as part of the revenue share program.

The P40's best description in its place on the battlefield is "average". Average armour, average gun, and average mobility. For this reason, it can perform most roles of a typical medium tank in a flanking or support role, but should not be relied on to be a shield or a speedster. The P40 features a default tri-tone camouflage of yellow, green, and red-brown; colors not too unlike that of late German tanks.
