Overall, armour is extremely weak, as is to be expected from the PT-76 chassis. You cannot rely on the armour to save you in any circumstance, as almost everything in the 6.7-8.7 bracket can pen you at any angle, and at any range. The turret face averages around 35mm of armour, the the upper and lower glasis averages between 23mm and 45mm, and the sides are extremely weak, at only 13mm of armour. The frontal armour and the angles will protect you from as much as heavy machine guns and occasionally the stray 20mm round, but otherwise anything can and will penetrate. Even light machine guns can kill you from the side, so if you disable an enemy's main gun, be sure to avoid showing your vulnerable sides to enemy machine gun fire.

''Armor in this tank is pretty much non existing, the front of the tank being the only part that can resist high caliber machine gun rounds thanks to the armor layout, otherwise, anything else will pen the armor, however, thanks to the thin armor, most shells fuze will not activate, turning them into ap shells that with some luck, will overshoot and do minimal damage to the modules, this however should not be relied on, the crew and ammo is packed very closely to each other, so each and every shot aimed at this tank has a very high one shot potential.''

The AU-220 cannon is extremely effective in the 6.7-8.7 BR bracket, as it can destroy any light tank at ranges up to 2.5km, most medium tanks up to 2km, and can reliably destroy heavies using weak-point sniping from 1.5km. In CQB, the cannon is devastating, and the 20g of TNT filler in the round ensure catastrophic damage from a successful penetration. The cannon performs best in CQB, or at ranges of less than ~1km. At range, use your laser rangefinder and pinpoint weak points, or aim for the vulnerable sides. Some things to consider remain, though, like the relatively low velocity of the round, the low penetration at ranges at 2+km (only 87mm at 0 degrees,) and the fact that you cannot reliably destroy heavies frontally. Unlike most tanks, it thrives best in an 8.0 uptier, where you face early MBT's with poor armour. Plus, the cramped crew compartments of 8.0 tanks allow for consistent one-shots from the sides.

Thanks to the high elevation angles of the main gun and turret turning speed, this coaxial 7.62 machine gun can actually be used against airplanes, however, the low caliber proves to have difficulty damaging planes at this BR, and would be more effective to use you main cannon instead, this mg can be used against very low armored IFVs and open topped vehicles with their crew exposed.

The PT-76-57 performs extremely well in the light tank support vehicle role, or as a flank-and-spank type of vehicle. In smaller maps, try to avoid face-to-face confrontations with heavy tanks, as it will quickly get you killed. Instead, try to secure a good position near a cap point, or flank to a side route to shred passing tanks. As a support tank, stick with friendly tanks, scouting and helping to repair as needed. Disable tanks for allies to kill when you can't, and destroy more lightly armored targets. This tank performs exceptionally well as a flanker as well, as it is fairly mobile and can easily kill tanks from the sides. If a more aggressive playstyle suits you better, rush a cap point, find a secure position, and destroy enemies pushing into it.  
+
This tank is a flanker through and through, as most tanks in this BR will have no difficulty pening and destroying this tank, so it's recommended to use your speed and maneuverablility to flank your enemies and show them how efective your gun is at taking them out through their sides.  
  
−
====== Notable Enemies: ======
+
'''''Downtier'''''
−
[[M46|'''M'''46]], [[M60 (Family)|M60]] - These American mediums are abundant at this BR, and cannot be reliable killed from the front. Disable the main gun and mobility first, then shoot the cupola to kill ~ 2 crew. If it is safe to push, get a sideshot for a crew knockout or ammo. Make sure not to expose your sides to machine guns.
 
  
−
[[T26E5|T26]], [[T34]], [[T32 Heavy Tank (Family)|T32]] - These American heavies cannot be killed frontally quickly enough to avoid return fire. Either flank the sides to cook the ammo, or disable and let allies pick them off.  
+
When dealing with tanks from BRs between 6.3-7.3, the user can have a more cheeki atitude when playing this tank, taking full advantage of your fully stablized gun, you can turn a corner at full speed surprising your enemies, and taking one or two of them out with your rapid firing gun, turning this tank into a glorified M18, this strategy proves effective against non stabilized enemies like the american tanks, However, this tactic shouldn't be used against stabilized enemies like the british with their centurions, as they can simply shoot at you with ease on the move.
  
−
[[SPz BMP-1]], [[BMP-1]] - These fast, mobile light tanks can easily kill with the 75mm anti-tank gun, or there missiles. Luckily, they are easy to kill, as 1-2 rounds will usually either destroy the ammo or knockout the small crew.  
+
Another tactic as mentioned above, is to use this tank as a better m18, just be wary that you are significantly bigger, and less armoured, and has a slightly worse mobility, this tactic is especially useful when dealing with big open maps, use the hills, houses, everything that can conceal your tank while you are on the move and ambush your enemies.
  
−
[[M48 Patton (Family)|M48]] series - These tanks can be killed frontally, or from the side, or the rear of the turret. However, with powerful weaponry and decent armor, they can easily kill you. Most of them also have rangefinders, so distance is not a sure way to protect yourself.
+
'''''Uptier'''''
  
−
[[Tiger II (Family)|Tiger II]] - This tank is heavily armored, has a powerful gun, and excellent surviveablity. Ideally, you only face them from the side, where you can easily penetrate. However, from the front, you need to go in this order: Disable the main gun, then break a track, and then knockout crew by shooting the commanders cupola. This will kill at least 2 turret crew.
+
This is where this tank struggles, the stabilizers start to become common sight around this Br and will prove almost impossible to surprise your enemies using the previous tactic, so this tank should be used mainly as an ambusher when in an uptier, use your speed to get into a position that has good view of a enemie common path early in the round, and wait for them, wait for most of them to pass so you can take as many of them out with your quick firing gun.
  
−
[[Kugelblitz]] and [[Wiesel 1A4]] - These German AA's can shred you from any angle and most ranges, so beware. However, you can kill them just as easily, so be aware of your surroundings. The Wiesel is exceptionally dangerous because of it's mobility and small size, so it can take key positions and show up behind friendly lines quickly.
+
if you manage to get on top of hill that can see distant enemies, use your laser rangefinder, this will give full precision when shooting at enemies with a distance of 1km+, proving this tank is quite an effective sniper as long as you can hit their sides.
−
 
 
−
[[Centurion Mk.5 AVRE]] - This HESH lobbing medium tank is one of your most dangerous enemies, because even a hit NEAR your tank will cause an overpressure kill. However, the long reload makes it extremely vulnerable for an extended period of time, and the commanders cupola will kill turret crew. Make sure to disable the barrel first, though, or you will see the hanger screen very quickly.
 
−
 
 
−
[[Marder A1-]] and [[DF105]] - The Marder has missiles and a rapid fire autocannon - two things that don't match with the PT-76-57 very well. The DF105 has a powerful HEAT-FS round that will one shot you instantly. Again, powerful light tanks are a major threat and a top priority.

Description

The PT-76-57 is a premium gift rank V Soviet light tank with a battle rating of 7.7 (AB) and 8.3 (RB/SB). It was introduced during Update "Direct Hit" as a reward for Battle Pass: Season V, "River Hunter".

Otherwise known as the PT-76E, the PT-76-57 possesses many significant upgrades, including night vision and a two-plane stabilizer. The main difference is the armament, a rapid firing AU-220 57 mm 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. 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-armoured foes or tearing through lightly-armoured IFVs and light tanks.

Notes:

  • As they are modeled by sets of 2, shells disappear from the rack only after you've fired both shells in the set.
  • Rack 2 is a first stage ammo rack (autoloader magazine). It totals 20 shells.
    • This racks gets filled first when loading up the tank and is also emptied first.
    • As the PT-76-57 is equipped with an autoloader, manual reloading of the gun is not possible.
    • Once the autoloader magazine has been depleted, you can't shoot until the autoloader has been restocked with at least 1 shell. The restocking time is much longer than the normal reload time of the gun. Take this into account when playing.
    • Simply not firing when the gun is loaded will move ammo from rack 1 into rack 2. Firing will interrupt the restocking of the ready racks.
    • The depletion order at full capacity is: 2 - 1.

Thanks to the high elevation angles of the main gun and turret turning speed, this coaxial 7.62 machine gun can actually be used against airplanes, however, the low caliber proves to have difficulty damaging planes at this BR, and would be more effective to use you main cannon instead, this mg can be used against very low armored IFVs and open topped vehicles with their crew exposed.

Usage in battles

This tank is a flanker through and through, as most tanks in this BR will have no difficulty pening and destroying this tank, so it's recommended to use your speed and maneuverablility to flank your enemies and show them how efective your gun is at taking them out through their sides.

Downtier

When dealing with tanks from BRs between 6.3-7.3, the user can have a more cheeki atitude when playing this tank, taking full advantage of your fully stablized gun, you can turn a corner at full speed surprising your enemies, and taking one or two of them out with your rapid firing gun, turning this tank into a glorified M18, this strategy proves effective against non stabilized enemies like the american tanks, However, this tactic shouldn't be used against stabilized enemies like the british with their centurions, as they can simply shoot at you with ease on the move.

Another tactic as mentioned above, is to use this tank as a better m18, just be wary that you are significantly bigger, and less armoured, and has a slightly worse mobility, this tactic is especially useful when dealing with big open maps, use the hills, houses, everything that can conceal your tank while you are on the move and ambush your enemies.

Uptier

This is where this tank struggles, the stabilizers start to become common sight around this Br and will prove almost impossible to surprise your enemies using the previous tactic, so this tank should be used mainly as an ambusher when in an uptier, use your speed to get into a position that has good view of a enemie common path early in the round, and wait for them, wait for most of them to pass so you can take as many of them out with your quick firing gun.

if you manage to get on top of hill that can see distant enemies, use your laser rangefinder, this will give full precision when shooting at enemies with a distance of 1km+, proving this tank is quite an effective sniper as long as you can hit their sides.

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.
  • Ammunition carousel layout increases detonation risk in the event of a centre-mass penetration.
  • Limited -5° gun depression restricts the tank's capacity in mountainous environment

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.
