Description

GarageImage Object 685.jpg


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

-The armour on the Object 685 is alloy ABT-101. The armour values in the chart are displayed in rolled homogeneous armour equivalency.

Armour Front (Slope angle) Sides Rear Roof
Hull 54 mm 16 mm 5 mm 6 mm
Turret 19 mm 16 mm 16 mm 8 mm

The Object 685 is a very lightly armoured vehicle. The alloy may at first appear to be somewhat thick, but it is much less effective than rolled homogeneous armour at stopping rounds. The Object 685 can be killed by almost anything, with .50 calibre machine guns able to penetrate even parts of the front armour at close range. Additionally, the Object 685 has hullbreak. The commander and gunner are somewhat far apart, but the object has only 3 crew, so survivability is not particularly impressive. Generally, Object 685 drivers should not rely on their armour in any situation.

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
  • Has amphibious capability: perfect for unexpected flanks, accidental dunks, and messing around

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.
