Specifically, the mismatch in crew values caused by commander's 10% crew skill bonus. Outside of a crew of 1 commander only, 100% crew is a fiction. The client values, given for 100% crew, will normally be taken into battle with 110% crew skill members aside from specific functions, causing their actual performance to deviate from the expected client value. These differences are taken into account in tooltip boxes.

The 121 is a Chinese tier 10 medium tank.

Development of a new medium tank based on the Type 59 began in 1962. The new tank was expected to feature improvements in firepower and armor protection. However, the project was canceled shortly after. Some technical innovations were applied later, in the development of the Type 69 tank. All 121 tank prototypes were destroyed during Chinese nuclear weapon testing.

The 121 continues the Chinese tradition of installing the largest gun possible on a medium tank. The 121 is an all round improvement over the WZ-120 with improved gun handling and DPM being the main benefits.

With its 122mm gun, the 121 excels in the peek-and-boom role, and may outtrade most other medium tanks or even heavy tanks. The armor might not lend itself to proper front-line use, but as always the soup-bowl turret and angled frontal plate will extend your survivability.

The 121 is a menacing opponent for any tank in a straight close-range brawl and is flexible enough to carry games with its raw damage output. Still, expect to struggle if not fighting on your own terms - the gun handling is nowhere near the best T10 mediums.


The 121 marks the end of its Chinese medium line.

Player Opinion

Pros and Cons

Pros:


  • Joint highest alpha damage in tier/class, good penetration
  • Very good DPM, good gun handling and accuracy
  • Strong turret armor and better hull armor than its predecessor WZ-120
  • Excellent hull traverse speed and good ground resistance, great agility
  • Low profile, good camouflage values


Cons:


  • Despite improvements, the hull armor is still unreliable
  • Bad gun depression, as usual for a Chinese tank
  • Poor aim time, comparable to that of a heavy tank


Performance

A straight upgrade from the WZ-120 and China's main counterpart to the Russian Object 430U, the 121 employs a similar playstyle to its predecessor, but with improvements across the board.

Most critically, the 121 "enjoys" -5 degrees of gun depression. While this would normally be a bad number, it is a significant improvement over the abysmal -3 degrees the WZ-120 had to deal with when using its top gun, allowing the 121 more freedom when choosing its positions on the battlefield. Alpha damage is still the highest in tier and class, tied with Object 430U and the Swedish UDES 15/16, and while HEAT penetration is the same as WZ-120, base AP penetration as well as shell velocity enjoy small but welcome upgrades. Accuracy, gun handling and aim time are also improved, providing an overall more comfortable experience for players who wished the WZ-120 had a less clumsy top gun. Also, the 121 has excellent DPM, with about 8 seconds reload with a fully trained crew, ventilation and a standard gun rammer. Unfortunately, the aim time is quite poor.

In terms of defense, the 121 retains a solid turret with small and well protected cupolas, and a thicker upper glacis compared to the WZ-120. When able to cover its hull, the 121 can be very hard to dislodge from its position, though the hull armor is quite unreliable and unable to withstand most return fire from same-tier guns, barring poorly aimed shots. The 121 also enjoys good concealment and has a low profile, so it can use cover effectively.

Mobility-wise the 121 is a mix of good and bad - it has good speed and excellent agility, but its engine power is low (improved somewhat as of 1.10.1) and acceleration can feel sluggish at times. Overall, it is still better than its main Russian competitor though.

All said, the 121 is a strong tank let down by some critical shortcomings, such as long aim time and lack of gun depression. This makes it unsuitable for top competitive gameplay, but a properly played 121 can be quite devastating so long as its strengths and weaknesses are understood.

  • As of Patch 1.10.1, the 121 has been buffed. While still unreliable, the thickness of the frontal hull has been increased from 120 to 135, improving the frontal hull effective thickness from ~195 to ~220. This makes it slightly more reliable, mostly against lower tiers. Additionally, the Health has been increased from 1,950 to 2,050. The engine power has also increased from 580 to 650, giving it 1.8 more hp/t. Lastly, the shell velocity and penetration of its AP shells has been increased, from 258 to 262 pen, along with 115 more shell velocity, from 1,000 to 1,115. However, the shell velocity of its premium HEAT shells and its HE shells has been decreased from 1,000 to 907.

Historical Info

Note: The 121 is not to be confused with the WZ-121, better known as the Type 69.

Background

The 121 was the first attempt of China to develop its own tank after the breakdown of relations between China and the Soviet Union. However, the project was considered too ambitious, and development instead switched to the Type 69, which itself was developed from a captured T-62.

The prototype 121 ended up being destroyed as a test vehicle during Chinese nuclear testing, along with the prototype WZ-132's. No pictures or blueprints of the tank survive.


Historical Accuracy Errata

The following are consensus errors or inconsistencies which have been identified with the configuration of the vehicle in question and conflict with information available on the public record. The causes for these divergences in the game are normally not disclosed and may be rooted in game balance.

As many of the data of the 121 were either lost or are still classified by the Chinese government, many of the technical aspects of the tank were made up by Wargaming.
  • The 121 is commonly mistaken for the WZ-121, the Chinese industrial designation for the Type 69 tank. The Type 69 was derived from the Type 59 and has no relation to the 121.
