The Object 685 is a rank VII Soviet light tank with a battle rating of 8.7 (AB/RB/SB). It was introduced in Update 1.91 "Night Vision".
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 equivalence.
|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
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.
Close Range Engagements:
The Object 685 can fare well at close range due to the excellent gun handling and reload rate. Additionally, the mobility of the vehicle allows it to easily outmanoeuvre enemies at close range. However, the thin armour and hullbreak means that getting shot is usually a death sentence.
Long Range Engagements:
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.

Pros and cons
- Powerful rounds with a fast reload
- Good mobility
- Scouting ability
- Thin armour avoids excessive spalling
- Thin armour
- Lack of thermal sights
- Small crew
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.
