General info

The ASU-85 in the garage.

The ASU-85 is a Rank IV Russian tank destroyer with a battle rating of 6.3. It was introduced in Update 1.59 "Flaming Arrows". It's low profile and extremely potent gun makes it a wonderful contender in the 6.7 BR range. However, the lack of armour makes it hard use this vehicle in open environments at its BR. Everything will become easier when you unlock the HEAT-FS shell with 300mm penetration at any distance.

The main purpose, usage and tactics recommendations

General play style

The stock shell is good. 230mm penetration is enough for weak spots in Rank IV. It is recommended to get the HEAT-FS shell as soon as possible for the ultimate 300 mm penetration for the vehicle. Beware of any incoming fire however, the armour is weak at only 45 mm thickest at the front. The mobility is mediocre, remember to cover flanks

  • Sniper: This tank doesn't surpass other snipers in Rank IV, due to the lack of armour. Utilize all possible mechanics to aid in acquiring and ranging the targets, especially the binoculars and range finder modification.
  • Ambush: Find somewhere in the map that you feel most of the fight will happen there, find a good view with nice covers at there. Or just sitting in some bushes near the flanking routes.

Vehicle characteristics

The ASU-85 has a rather unorthodox method of using it's smoke screen. Unlike most vehicles, which use smoke shells, singular canisters, or canister clusters, the ASU-85 uses two large drum like structures at the rear. When deployed, these will drop away, so it's relatively easy to tell from close range whether or not an ASU-85 has smoke or not, and how many it has.

Be wary of the this method of deployment, as due to the orientation of the drums, the smoke screen will actually form behind the tank, and take about 2-3 seconds to fully envelope you.

Tactics

  • Urban map: ambush, shoot-and-scoot. 2 main tactics with this tank in urban map. Beware flankers like the M18 Hellcat, Panther 2, Centurion Mk3.
  • Field map: sniping, of course. You should have the HEAT shell ASAP

Specific enemies worth noting

  • Tiger II (P), (H), 105 mm: Shoot at the turret cheeks (only front weakspot). If the HEAT shell is available, shoot the HEAT straight into their hull.
  • Panther II: Use HEAT against hull if it is at a close range and is looking right at the vehicle. In a longer distance, try for the lower glacis and the turret cheeks
  • T29: Shoot the lower glacis if engaging it frontally. There are a few weak points in the front turret as well, look for them.
  • Caernavron: Fire at the turret ring and lower glacis.
  • A39 Tortoise: Aim towards the machine gun port on the left side, there will be a weak point present.
  • T95: Aim towards one of the two commander cupolas on the roof. Try to aim at its side so that the penetrating shell can detonate inside and severely damage the crew.
  • Jagdtiger: A well-protected armoured beast. If caught in the front, try to engage it with HEAT shells, preferably at the lower glacis.
  • M26E1: Though dangerous towards the ASU, its armour is similar to the M26 Pershing and could be easily taken out by a good shot on the front hull.

Counter-tactics

The ASU-85 is a casemate tank destroyer, but one with little armour. As such, the enemy will most likely attempt to use the vehicle from a long-range or from within cover, in both situations waiting for tanks to ride into its crosshair for it to get a shot at it. With access to a lethal HEAT-FS round, the ASU-85 can cause some serious damages if it is allowed to fire a round.

Luckily, due to its weak armour, it is a breeze to take out the tank. Simply land a solid shot onto it before it could get a chance to get a shot at you. Even aircraft with a sufficiently powered cannon armament could penetrate through the ASU-85's roof armour.

Pros and cons

Pros:

  • Powerful 85 mm cannon, more powerful than the T-34-85 ones
  • Access to HEAT-FS rounds with 300mm penetration
  • Tiny profile
  • Decent ammo storage for size
  • Access to a coaxial machine gun
  • Medium gun muzzle velocity

Cons:

  • Slow gun alignment
  • Barely any armour, MG rounds may penetrate
  • Reverse speed somewhat slow, hard to make hasty retreats.
  • Mediocre mobility
  • Bad gun depression

History of creation and combat usage

Development

A new assault gun was requested by the Armed Forces sometime before 1953. Due to the success of the ASU-57, they tasked the OKB-40 design bureau headed by Nikolaj Astrov to design the vehicle. The design, designated Object 573, was ready for tests in the latter half of 1953. Constant changes and improvement was made from the span of 1956 to 1957. The design used the chassis of the PT-76 amphibious light tank design, though it did not have the same amphibious feature and had a new engine propelling it. The armament was an 85 mm D-70 gun derived from the 85 mm D-48 anti-tank gun. The design could carry 45 rounds inside and could fire a variety of rounds up to 1 km away. Secondary armament for the vehicle was a GMT or PKT coaxial machine gun. The improved design was going to accepted and enter production in 1958 as the SU-85 (despite the existence of a vehicle of the same name), but this was again delayed when the Ministry of Defense ordered an armoured roof to be installed. The design was to enter production in 1961, but by then the design was rather outdated for army forces usage. Thus, when the vehicle entered production, it was taken up by the VDV, the Soviet Airborne Forces, and renamed the ASU-85. The ASU-85 was produced from 1959 to 1966, while staying in service from 1959 all the way to 1993.

Usage

The Soviet airborne forces primarily used the ASU-85 as a light infantry support/assault gun. Advancements in air-drop techniques and the advent of helicopters made its air deployment a more viable option in the early 1960s. The Soviet Union deployed 31 ASU-85s to each of its airborne divisions in and assault gun battalion. The Soviet Union used the ASU-85 during the Soviet-Afghan War with the airborne troops stationed there.

The ASU-85 was only given out to Poland and Vietnam. Poland used the ASU-85s in the same manner as the Soviet Union, with 31 vehicles in each airborne divisions. The ASU-85 are still in service in the Vietnamese military, with interests on improving their technical performances in early 2016.[1]

The ASU-85 also serves as the genesis of other support vehicles using the derived PT-76 chassis. The most notable vehicle using a similar chassis was the ZSU-23-4 "Shilka" anti-aircraft system.
