There aren't many medium tanks in the game that feature such a massive gun as the T-34-3. Of course, such firepower means that there are other drawbacks, and you can rest assured that the Chinese vehicle doesn't play like a conventional medium tank. Time to take a closer look!
The T-34-3 shares the same hull and turret armour as the famous Type 59, so you can already guess that this vehicle is quite tough against same and lower-tier tanks. Side-scraping also works to a certain extent, but be careful: show too much of your side, and you'll risk receiving damage where your ammo rack is located.
Another thing is that your gun depression is not great; a usual disadvantage for Chinese vehicles. When peaking over hills, you'll have to expose most of your tank to be able to land a shot, and it's very likely that you'll always get damaged in return. Try different positioning – on lower ground you won't have as many issues with gun depression.
As the 122 mm gun is rather powerful in terms of damage, it comes at a price of accuracy, aiming time, and reload speed. This means for you that your armament is only effective at close range, and you can't count on reliably hitting anything further than 200–300 metres away. Your amazing damage per shot, paired with long reload time, means that you are more likely to win encounters if you trade shots with your opponents.
Considering the long reload time, aiming time and huge dispersion, this set of equipment is absolutely perfect for the T-34-3. Improved Ventilation may improve all different vehicle parameters, but the effects are not as noticeable as with these pieces of equipment.
While the T-34-3 is not your standard medium tank, the choice of crew skills and perks is still similar. In fact, Snap Shot, Smooth Ride, and Safe Stowage have an even bigger effect on this vehicle, because of the massive dispersion and weak ammo rack.
