Design

The BTR-90 is a wheeled IFV that was first designed in early 1990s for the Russian military. It is designed to fulfil a wide range of roles ranging from providing fire support for dismounted troops to reconnaissance duties.

Armament
It is fitted with a 30 mm autocannon that is capable of firing both high-explosive and armour-piercing rounds at distances of up to 1,500 metres. In addition to its primary cannon and 7.62 mm coaxial machine gun, the BTR-90 has an anti-tank guided missile launcher and a turret-mounted 30 mm automatic grenade launcher.

The standard loadout of the BTR-90 gives it 250 high-explosive (HE) explosive and 250 armour-piercing (AP) rounds for the main gun, for a combined total of 500 shells. The coaxial PKT is loaded with a single 2,000-round linked belt while the ATGM launcher has up to 8 wire-guided Konkurs missiles. Lastly, the turret-mounted AGS-17 feeds from a single 400-round grenade belt. It has no spare belts to reload from.

Features
The BTR-90 is essentially the Russian counterpart to the American LAV-25. Both are amphibious-capable armoured troop carriers, but the BTR-90 is superior when it comes to firepower thanks to its wide array of weapons. While the LAV-25 is practically powerless against Main Battle Tanks, the BTR-90 stands a fighting chance with its Konkurs anti-tank missiles, which can put a stop to even the toughest of MBTs like the M1A1 after two or three direct hits.

Drawbacks
Because the BTR-90 relies on wheels for locomotion and is still lightly armoured (at least when compared to the BMP-3), caution is still advised when tackling any vehicular or AT infantry threats since the BTR-90 is quite soft-skinned and won't last long in a prolonged fight. When going up against heavy armour, the BTR-90's crew will need to make use of defilade and remain on the move in order to flank enemy tanks.

Crew Capacity
The BTR-90 has a crew of three personnel consisting of the driver, a gunner, and the commander. It can transport up to seven passengers at a time who can enter the vehicle via the hatches located on either side of the hull.

Variants

• BTR-90 (HQ)*

Stripped down version of the baseline BTR-90 with its turret armament removed and replaced with a single hatch fitted with a fixed (but rotatable) PKT machine gun. The PKT is loaded with a single 100-round belt box and has a further four boxes left in reserve.

This variant cannot transport any passengers and is restricted to carrying its driver and commander only, who doubles as the vehicle's gunner.

(*) The BTR-90 (HQ) is completely non-functional in normal gameplay and serves only as a deployable command vehicle in Capture The Island (CTI) scenarios created with the Warfare module.

Protection

Both variants of the BTR-90 have base armour values of 150.

Successful strikes to any of the following highlighted sections will inflict full damage to the component:

LEGEND
Green = Body
Orange = Engine
Violet = Fuel tank
Maroon = Turret

Note that with the exception of the turret, component hitzones remain identical on the BTR-90 (HQ) variant.

Body

Their hulls can resist up to 150 points of damage.

Engine

BTR-90 engines can survive 300 points of damage before failing. At least 20% of damage is shared with the vehicle's main "health" pool.

A damaged engine will prevent BTR-90s from being able to attain their top speed.

Fuel tank

The fuel tanks on both variants can withstand 150 points of damage before rupturing. No amount of damage on the tanks are transferred back onto the BTR-90's "health" pool.

Incurred damage will cause the vehicle to gradually leak fuel over time.

Wheels

The wheels on both BTR-90s can only take 60 points of damage. Destroying them will not affect the vehicle's "health" pool.

Turret

The regular IFV variant's turret incur up to 120 points of damage. 100% of incoming damage is always shared with the BTR-90's "health" pool.

Disabling the turret will prevent the gunner from freely adjusting the turret's rotation/elevation but does not stop its weapon systems from being utilised.

Armament

NOTE: For specifics on the 2A42's munitions, see its related section listed here.

The gunner position controls all weapon systems on the IFV variant. In the case of the HQ variant, the commander mans the externally fitted PKT machine gun instead.

For optics, only the gunner and commander on the baseline IFV model have access to optics with magnified/enhanced vision modes. The gunner can toggle a day, night or white-hot/black-hot thermal vision modes (the commander utilises black-hot/white-hot instead):

2A42

NOTE: Only available on the baseline IFV variant.

General-purpose 30 mm autocannon. It can switch between either HE or AP-type munitions. There is no delay when swapping between the two munitions types.

It can attain a variable fire rate depending on two modes:

• 200 rpm: 200 rounds per minute
• 550 rpm: ~ 550 rounds per minute

Both modes have identical dispersion values of 0.0005 rad regardless of distance. It can be manually zeroed starting from a minimum of 100 m up to a maximum of 1800 m. Adjustments are made with increments/decrements of 100 m.

Konkurs 9M113

NOTE: Only available on the baseline IFV variant.

Damage type	Base damage value	Maximum speed (m/s)
High-Explosive Anti-Tank	480	200

Anti-tank guided missile launcher mounted above the turret.

There is a fixed delay of 30 seconds in-between launches. Missiles have an initial launch velocity of 80 m/s. After 1.5 seconds of flight time, the missile will gain a maximum velocity of 200 m/s. It takes up to 30 seconds to reload a fresh batch of missiles (assuming the BTR-90 has run out and is rearming from a logistics truck).

Its seeker only supports manual SACLOS guidance and can be controlled up to a maximum distance of 4,000 metres. The warhead itself has a blast radius of only 1.2 metres.

AGS-17

NOTE: Only available on the baseline IFV variant.

Damage type	Base damage value	Aerodynamic friction	Initial velocity (m/s)
High-Explosive	13	-0.001064	185

Automatic grenade launcher. Effective against groups of infantry and unarmoured/lightly armoured ground vehicles.

The AGS-17 has a fire rate of 150 RPM, a dispersion value of 0.006 rad, and has an effective range of up to 1,500 metres. It takes 30 seconds to reload another belt of high-explosive (HE) grenades.

PKT

Base damage value	Aerodynamic friction	Initial velocity (m/s)
12	-0.00096	855

Mounted adjacent to the primary autocannon or as a standalone turret ring weapon, the PKT medium machine gun is accurate at distances of up to 800 metres.

It can attain a fire rate of up to 800 RPM and has a muzzle velocity of 855 m/s. Accuracy-wise, dispersion is always fixed at 0.00125 rad regardless of range. It takes 5 seconds to finish reloading a fresh linked belt or belt box.

Trivia

• Unlike the LAV-25, the BTR-90's gunner position was not "upgraded" with the ability to use thermal optics even after the release of the Operation Arrowhead expansion pack.
  • This was changed with the release of the latest Steam version patches (as part of the Community Configuration Project/CorePatch updates). Both the commander and gunner were finally given access to thermal vision optics.
  • CorePatch also granted the ability for the driver and gunner to switch positions (it was not possible to do so at release).
• Before the release of Patch 1.03, passengers seated in the troop compartment had glitched animations that caused them to appear as if they were crouching rather than sitting down.
• The BTR-90 is unauthentically portrayed in-game as the primary wheeled IFV of the Russian military. In reality, the BTR-90 was only procured in very small numbers, with the Russian Ministry of Defense (at the time) opting to upgrade the existing fleet of "BTR-80" IFVs to the "BTR-82A" instead.
