The '''{{Specs|name}}''' was a proposed replacement for the PT-76. It competed with two other designs, namely Object 788 and Object 934. The project's notable requirements were to develop a vehicle with a maximum combat weight of 15 tons, armed with a rifled 100-mm gun, an 9K111 "Fagot" anti-tank missile system, and a 12.7 mm machine gun. The project's protection requirements included anti-nuclear features like automatic sealing and air filtration capabilities, and the ability to withstand up to 23 mm AP rounds. Object 788 was disqualified for not including the 9K111 "Fagot" anti-tank missile system, trench-digging equipment, and a water-jet propulsion system. However, both Object 934 and {{Specs|name}} managed to pass the initial design evaluation, suggesting that they showed promise despite lacking certain components. It is likely that these designs were later taken into consideration for modifications and improvements to incorporate the missing criteria. Nevertheless, the production was eventually abandoned because they were unable to garner enough interest to continue. Still, later Soviet AFV designs made extensive use of many of the components and design solutions found in Object 934 and {{Specs|name}}, showing that their potential was recognized and put to good use.

The {{Specs|name}} was introduced in [[Update 1.91 "Night Vision"]]. It is a powerful and versatile vehicle that is well-suited for flanking. It features excellent forward mobility, a 6-second reload cannon, and a sufficient 3BM25 shell. However, its main drawbacks are its subpar survivability, lack of thermal sights, and poor gun depression. Even despite that, the {{Specs|name}} remains a good choice for players who prefer a more careful yet aggressive and fast-paced playstyle.

'''Notes:'''
+
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.

Mobility wise, the Object 685 can be considered as a slightly heavier [[Object 906]] compensated by a noticeable stronger engine and a different gear box (note the missing reverse gearbox). It is not slow but is not the fastest light tank at the battle-rating. When downtiered, it is able to be faster than most tracked vehicles (most of them reach as most 65 km/h while this can reach more than 70 km/h) with exception of the [[Rooikat 105]], [[Rooikat Mk.1D]] and [[Radkampfwagen 90]]. It's suspension is a relatively soft suspension, meaning it will not damp as much in rough terrain but due to its thin tracks, the surface the tracks have on the floor make it be relatively slow on snow and sand (but faster than many tracked vehicles). It is fully amphibious which makes the Object 685 capable of crossing water bodies which can give an advantage (Eastern Europe river for example) but the speed while on water is lacklustre.

The Object 685 has the same ballistics as the [[D-10T2S (100 mm)|D-10T2S]] 100 mm cannon even sharing the same ammunition. Thus, the use of the gun should be the same as the [[T-55A]]. The gun is capable of destroying all enemy vehicles it faces from the front (with exception of the [[Maus]] glacis) with its powerful APFSDS shell. Despite not having the most powerful dart at the battle rating, the 6 second reload of the autoloader makes the Object 685 a formidable quick firing tank, capable of destroying multiple enemies with relative speed.

'''Gameplay Stock:'''

The Object 685 is much less powerful when stock. It is equipped with the 3BK17M HEAT-FS shell, which is generally inferior to the 3BM25 shell. Another issue while stock is the mobility, which is not as impressive when stock. Another issue is the lack of the Airstrike modification, which makes spawning in air vehicles easier in ground RB after scouting.

The Object 685 is a highly mobile Soviet light tank which has an excellent cannon. Its disadvantages are thin armour and a lack of thermal sights. Object 685 players should avoid areas with heavy foliage, as the lack of thermals will prove detrimental in these areas. The best strategy with the Object 685 is flanking the enemy team using the Object 685's mobility. The amphibious capability can help create new avenues of attack when flanking. The scouting ability also helps the team while on the flanks. One tactic to avoid in the Object 685 is using the ESS system, as enemy thermal sights can see through the smoke, while the Object 685 will effectively blind itself.

The Object 685 may have difficulty in prolonged long range engagements. The main armament is excellent, but the Object is held back by its lack of thermal sights and low survivability. The lack of thermals means that seeing your target may be difficult at long range. Additionally, the low survivability means that the Object 685 will not survive most hits, even at long range.

In the 1970s, the Russian Ministry of Defense opted to create a replacement for the PT-76, the main to contestants being the PT-85 (also known as Object 906) and the Object 685. It was tested but did not enter service or combat. It featured components that were later used for multiple vehicles, this being the Object 688 (which ended being the BMP-2), BMD-3 and 2S25 Sprut-SD (based on BMD-3). It was made for airborne units to maintain the armoured section of airborne units, at the time those being PT-76, BMD-1 and ASU-85. It featured a greater weight than the PT-76 due to the size and main gun but featured a more compact suspension due to being a telescopic hydraulic shock absorbers and suspension.

Object 685 X-ray view in hangar

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.
