== Description ==

The '''{{Specs|name}}''' is a premium gift rank {{Specs|rank}} Soviet light tank {{Battle-rating}}. It was introduced during [[Update "Direct Hit"]] as a reward for [[Battle Pass: Season V, "River Hunter"]]. Otherwise known as the PT-76E, the 57 possesses many significant upgrades, including night-vision and a two-plane stabilizer. The main difference is the armament, a rapid firing AU-220 57mm cannon fitted in a unique turret which, using the same BR-281 shells used in the [[ZSU-57-2]], proves very effective when dealing with numerous enemies at once. No doubt often compared to the ZSU-57-2 due to the similar armament, the PT-76-57 makes up having only half the firepower by instead having a significantly faster rate of fire. On a relatively mobile and low-profile chassis, the PT-76-57 can be a true menace on the battlefield when flanking otherwise heavily armored foes or tearing through thin-skinned IFV's and light tanks.

=== Survivability and armour ===
{{Specs-Tank-Armour}}

''Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat? If necessary use a visual template to indicate the most secure and weak zones of the armour.''

''Give the reader information about the characteristics of the main gun. Assess its effectiveness in a battle based on the reloading speed, ballistics and the power of shells. Do not forget about the flexibility of the fire, that is how quickly the cannon can be aimed at the target, open fire on it and aim at another enemy. Add a link to the main article on the gun: <code><nowiki>{{main|Name of the weapon}}</nowiki></code>. Describe in general terms the ammunition available for the main gun. Give advice on how to use them and how to fill the ammunition storage.''

== Usage in battles ==

''Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).''

=== Pros and cons ===

''Summarise and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in a bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".''

'''Pros:'''

* Rapid firing 57 mm autocannon can deal huge damage in a short amount of time
* Two-plane stabiliser grants it the ability to fire first, compared to most opponents which lack stabilizers
* 5-14x gunsight zoom is great for both short range and long range engagements
* Fast -17 km/h reverse allows it to pull out dangerous situations in time
* ~150 mm penetration plus 20 g TNT filler is deadly for sideshots
* Has both smoke grenade launchers (2 salvos) and ESS
* Is amphibious

'''Cons:'''

* Inherits the PT-76 hull, meaning extremely poor armour
* ~150 mm penetration will struggle against late/cold war heavy tanks like [[M103]], [[Conqueror]], [[Maus]], etc.
* Ammo placement all but guarantees a detonation in the event of a center-mass penetration.

== History ==


In the early 2000’s, the issue of increasing the combat effectiveness of the numerous, but outdated PT-76’s was proposed to be solved in a very non-trivial way. Engineers of the Nizhny Novgorod design bureau "Burevestnik" combined the 57mm automatic gun developed in the USSR at the end of the 70’s with a mechanized ammunition rack, combining this in a combat module for a specially created turret for light tanks of the PT-76 series. While considering possible ways to re-equip old amphibious tanks with a new weapon, the small-caliber automatic cannon, although it was inferior to other variants of larger calibers in terms of armor penetration, gained a lot in terms of the burst weight to time ratio, as well as in possible applications - from destroying armored vehicles (including a modern MBT when hit to the side) to fighting helicopters.

The AU-220 module itself, built on the basis of the Soviet S-60 anti-aircraft gun, has already been proposed for the fleet in the form of a remotely controlled shipborne mounting. For use on armored vehicles, the module was equipped with a modern fire control system with night vision devices and a laser rangefinder. The prototype PT-76 with a 57mm gun, remained at a stage as a working prototype, however, the AU-220M module continues to exist as a promising solution for the latest vehicles in the Russian army.
