The Object 257 is a Soviet tier 9 heavy tank. A project of the heavy tank designated IS-7 that was developed in 1945. The vehicle was supposed to feature an electromechanical transmission. Development was discontinued at the documentation design stage. Existed only in blueprints.
The tank is a major armor upgrade from the IS-3. You will bounce a lot of shells with it. Some folks prefer the top gun from the IS-3 (BL-9) over the upgrade gun (BL-13). The reason for this is the BL-13 uses APCR for it’s standard load. And the APCR has problems with normalization against armor. There is also a price difference from standard AP, but that is minimal at about 900 credits more per round. Experiment with both guns to see which you prefer, as the upgrade gun must be unlocked to get to the improved turret and the IS-7.
Try to bait enemies into firing into your side armor by tanking in a 45° angle. Due to the “strange” armor layout beneath the outer plates many shells get absorbed and deal zero damage — the side armor is nearly impenetrable to HEAT rounds because of this. Over-angling while sidescraping is very forgiving and track shots are less likely to do damage because of the very high ground clearance.
The Object 257 tends to lose its ammo rack and driver when penetrated in the pike nose, so safe stowage is a skill you might keep in mind (the IS-7 also needs it).
With its thick armour and V-shaped armour, world of tanks obj 257 can bounce shells like no other tank and it’s almost impossible to be destroyed by lower tier tanks. If the vehicle is introduced to the game on the current state, it might become a game-breaking vehicle. Object 252U, also know as Defender, has a very similar armour shape and is currently considered overpowered for it’s Tier, Object 257 takes what is good on Object 252U and takes it to the extreme.
Being a breakthrough combat vehicle, the tank usually faces the enemy with its front side, so this is naturally in most cases the part with the thickest armour, both on the turret and the hull. Its sides and, above all, the rear are a different story, though. Therefore, the easiest way of damaging a tank – especially of the heavy class – is to attack it from the flank or from behind. Here’s why exactly:
- Tank sides: Attacking the enemy vehicle from the side has numerous advantages. The most obvious one is the much thinner armour of that part. This means that your shells will have an incomparably higher chance of penetrating and dealing damage, even if they’re of an inferior caliber. What is also important, tanks are much bigger from the profile than from the front, so catching an enemy vehicle from the flank gives you a bigger and thus easier target to hit. Last but not least, shooting at the sides creates more opportunities of damaging the enemy’s modules and injuring their crew members. Remember, damaged modules or a knocked out crew translate to a reduced combat effectiveness of the enemy vehicle.
- Tank rear: This is the most vulnerable part of any tank and the ultimate gift for any gunner blessed with the opportunity to fire some shells at it. Being in most cases only lightly armoured (if at all), shooting the rear means guaranteed damage almost every time. Additionally, mind that this part of the tank is the place where the engine compartment is located. As a result, landing shells there may additionally damage this module and, with a bit of luck, set the enemy vehicle on fire, causing extra damage every second until the fire is put out.
