Italy is the currently newest nation presented in World of Tanks, after Poland.
Currently there are three end-tier lines - medium tanks, heavy tanks, and tank destroyers.
Italian medium tanks, from tier I to VII retrace the history of the nation’s tankbuilding, from Italy’s early tank designs at lower tiers through to post-WWII machines at mid-to-higher tiers. These vehicles generally have acceptable protection and decent firepower, yet their mobility leaves much to be desired. It would be best to play them as supporters, much resembling the German mediums at their tier. But the cherry on the cake are Tiers VIII–X with a new gun system, a hybrid between an autoloader and a regular gun. This Italian revolver of sorts, called an “autoreloader,” can automatically reload a shell in the drum even when the drum is not empty yet. Combined with the great gun handling and good mobility, they could perform no less effective than Czech or French autoloaders, but are easier to handle. Also as a common trait of post-WWII western tank designs, they possess good - if not great - gun depression, which can be advantageous on hills or slopes.
Italian heavy tanks, start at tier VII with a traditional single shot, quite slow and not too much armored heavy tank, and evolve into an unusual support line from tier VIII to X. These vehicles possess a unique variant of the autoreloader system found on the medium line, called "improved autoreloader", which after the first shot fired, allows them to decrease the reloading time of the next shot, the more its firing comes close to the complete reload (to a maximum of half the time). Other key features of these vehicles are the decent mobility for their tiers, the not so great frontal armor (even if quite sloped), and good gun depression paired with high damage and high shell velocity guns at the expense of overall accuracy. These tanks shine the most in hulldown positions maximazing the turret armor thickness, and against enemies with low health, becoming a particularly dangerous threat in the final stages of a match.
Italian tank destroyers, starting at tier V, possess some of the most unique and particular features of the entire game. The first two tanks at tier V and VI, are typical tank destroyers based on real vehicles built in Italy during the war, with very low profiles, average mobility, low armor and comfortable single shot guns housed in a fixed casemate, which are best used as typical low tier snipers. But from tier VII to X, they completely transform into big and menacing assault tank destroyers with very high frontal armor, a partially rotating turret, low mobility and powerful guns with a completely new autoloader mechanic, characterized by a fast reload time of the magazine and long time between the shots. Their drawbacks consist in low mobility and top speed, low penetration of standard shells (which makes them prone to the use of premium ammos), and horrible gun handling. Using them on the frontline with good positioning is the key to make the best use of their strengths minimizing their weaknesses.
