Description
The SK-105A2 is a rank VI French tank destroyer with a battle rating of 8.7 (AB/RB/SB). It was introduced in Update "Ixwa Strike".
General info
Survivability and armour
The hull armour of the SK-105A2, even though it is angled at 62°, is relatively weak. In most cases, it will stop 20 mm cannons but cannons with a bigger calibre will have no problems punching right trough the hull armour which in most cases leads to an instant death, as the crew is sitting tightly packed together. Rapid firing autocannons such as the ones mounted on the Gepard or the ZSU-37-2 will have no problems shredding the SK-105 in less than a second. It is highly recommend to not take more than 24 shells due to the fact that reserve shells pile up in the front most part of the tank, which might lead to even more frequent instant deaths. If the user can manage their rounds effectively, the safest ammo count would be 16. This way, only 4 extra rounds are placed into the turret and no rounds are in the front of the tank.
Armour type:
- Cast homogeneous armour (Front of the turret, Gun mantlet)
- Rolled homogeneous armour (Hull, Turret roof)
| Armour | Front (Slope angle) | Sides | Rear | Roof |
|---|---|---|---|---|
| Hull | 20 mm (62°) Front Glacis 20 mm (49°) Bottom Glacis |
14 mm Top hull side 14 mm Bottom hull side |
12 (1°) mm | 5-10 mm |
| Turret | 20 - 40 (16-69°) mm Turret front 40 mm (0-90°) Gun Mantlet |
20-40 mm | 10-20 mm | 10 mm |
| Cupola | 10 mm (60°) | 10 mm | 10 mm | 10 mm |
Notes:
- Suspension wheels and torsion bars are 15 mm thick
- Tracks are 20 mm thick

| Realistic | 68 | 9 | 283 | 320 | 15.72 | 17.78 | |
The SK-105 has an exceptional speed of about 59 km/h forwards on roads, and around -9 km/h in reverse while also being relatively manoeuvrable, as it is very similar to the AMX-13 light tank. It is powered by the Steyr 7FA/6-cylinder turbocharged diesel engine which provides 320 hp (238 kW) for a power-to-weight ratio of 18 hp/ton. While it can go as fast as 59 km/h, one should expect to move at about 40 km/h off-road, however the reserve speed still stays at -9 km/h and it takes roughly 12 seconds for the SK-105 to rotate 360° in neutral steering.

Armaments
Main armament
In terms of weaponry, the SK-105 carries the 105 mm PzK M57 which is very effective at dispatching almost every enemy tank with a well placed shot. It possesses a 4-second autoloader with a magazine size of 12 rounds. After the 12 rounds were depleted, the user has to wait until the magazine houses at least one round. This can be quite problematic if one is too trigger happy.

Machine guns
The SK-105 has access to the MG3A1 (7.62 mm) machine gun. While it lacks any some sort effective penetration, its high rate of fire can dispatch exposed crew members easily. The one, and only, belt houses 1,000 rounds with average velocity. It is largely inadequate against armour and should be used exclusively to dispatch exposed crew members or to destroy environmental objects such as fences with ease.

Usage in battles
The SK-105A2 excels at filling the spot as a sniper, due to its very powerful 105 mm cannon, low profile and high mobility. This is all balanced out however by the fact that the SK-105 possesses little to no armour, so any kind of hit from a cannon more powerful than 20 mm, will dispatch the SK-105 quite easily. The user should always check their surrounding as much they can, and as frequently as they can. Finding a vantage point with cover nearby is an effective strategy. Brawls and rushes should generally be avoided and tactics like flanking or sniping should be focused upon as the SK-105 will stand no chance in direct engagements or close quarter fights. However, if one does stumble into a brawl, the 4 second autoloader will prove to be a major benefit coupled with the amazing 105 mm cannon, although one should pay attention to their magazine as the user will not be able to shoot at all if the magazine runs dry completely. It is because of this reason that at least 2 spare rounds should be carried in the magazine in case of an ambush. One big thing to note is that the user also lacks a stabilizer which may be a problem due to the light size of the tank and fast speed, as these properties will make the gun harder to stabilize on its own if the user decides to brake spontaneously.
Pros and cons
Pros:
- Very mobile and high top speed
- Good HEAT-FS stock round (OCC-105 F1)
- Small profile, easy to hide behind cover
- 12 round auto-loader; reloading takes 4 seconds
Cons:
- Lacks a stabilizer
- Little to no armour
- Easy to destroy with a single shot due to the tight crew placement
- If the magazine runs out of rounds, the user has to wait until it is refilled to engage
History
The SK-105 was developed by the company named Saurer-Werk, as the Austrian Army needed a reliable tank destroyer. The very first prototype was built in the year 1967 and it the pre-production began in the year 1971. Around 286 were made for the Austrian Army and was in service until the 1990s, while the rest of the SK-105s were exported. A Substantial amount of this vehicles still in service today, mainly in Brazil, Bolivia and Argentina to name a few, with the latter creating the "Patagon" variant, that merged a brand new hulls with surplus AMX-13 (105) Turrets, the result was a vehicle more comparable to the Sk.105 A1.

Because of their massive success and mass production of AMX-13 light tank, the Austrian army decided to contact France in the hopes of designing a new turret. In the end, France agreed and came up with an oscillating turret that was light yet powerful enough to be used in an anti-tank role.
