The Object 685 is a rank VI Soviet light tank with a battle rating of 8.3 (AB) and 8.7 (RB/SB). It was introduced in Update 1.91 "Night Vision".

General info

Survivability and 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.

Mobility

Write about the mobility of the ground vehicle. Estimate the specific power and manoeuvrability, as well as the maximum speed forward and backwards.

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:

  • Very good stock and unlockable shells
  • Can handle up-tiered situations
  • Great mobility
  • The nature of its thin armour makes penetrating shells cause minimal spalling, high explosive shells may not even trigger and when they do its usually already too late

Cons:

  • Compared to its predecessor, the Object 685 is less effective in just about every way except for its firepower and having thicker armour

History

After production of the PT-76 was discontinued, Soviet engineers began work on developing a suitable replacement around a set of requirements provided by the military. The requirements were sent to three different design bureaus, with each bureau developing its own vehicle around the given specifications.

One of the proposed designs, the Object 788, was disqualified early from the competition due to being incomplete and missing several key features mandated by the requirements. The other two designs, the Object 685 and Object 934 were both deemed as sufficient, and work on them continued. By the mid 1970s, both vehicles were built and tested, but neither managed to garner enough interest to warrant a production order being issued. Despite not making it past the prototype stage, design solutions from both vehicles were later applied to other Soviet fighting vehicles.
