General info

Survivability and armour

The Strf 9056, like the other non-upgraded CV90 vehicles (CV90105 and CV90120), has little armour, and low protection against hits. The basic armor plating can resist 12.7 mm/.50 BMG projectiles at range, but the armor is not to be depended upon and is only helpful with lucky positioning. It can resist some aerial attacks and artillery fire, but remains extremely vulnerable against incoming enemy fire.

As the Strf 9056 lacks the add-on modular armor of the 90C variants, it has a noticeably lighter feel on the move. The low weight combined with high-output Scania engine leads to an agile and swift moving vehicle, able to do sneaky flanking maneuvers and capable of climbing steep hills to get into ambush positions. When played right, the Strf 9056 is quicker than the Strf 90C, and is able to surprise enemies by showing up in unexpected places.

Armaments

Main armament

The Strf 9056, like the two other Strf 9040 variants (The Strf 90C and Lvkv 90C), is armed with a Bofors L/70 40 mm anti-aircraft gun repurposed as an omnipurpose (anti-tank, anti-aircraft) gun. The automatic cannon boasts a rapid fire rate, a magazine holding 24 shells, and a complete maximum load of 234 shells. The gun's internal 24-shell magazine is quickly replenished, and is usually enough to deal with both enemy armour, helicopters, and airplanes. It does however carry a risk of surprising the player by running empty - thanks to its high rate of fire. The shells carried are the same as on the Lvkv 90C - the spårljuspansarprojektil m/90 (APFSDS-T), spårljusspränggranat m/90 (HE-T), and kulspränggranat m/90 (HE-VT). The former two are stock shells - the latter is unlocked through research, on the 2nd tier for an RP cost of 18.000, and has a proximity fuze, very helpful against air targets.

The Strf 9056 also carries a 7.62 mm Ksp 39C, coaxial to the main gun, placed in its turret cheek. The most unusual armament is however the Robot 56 "BILL 2 - Bofors, Infantry, Light & Lethal". The dual-missile launcher, mounted on the right side of the turret, can be devastating to enemy armour behind cover. Its missiles fly above the point of aim, detonating above the vehicle, firing its explosively formed penetrator through the turret roof or engine deck, thus hitting areas with the lowest armor protection. A well-aimed hit can destroy a target in a single hit by igniting ammunition, igniting fuel tanks, or knocking out crew. The missiles do however have a limited range of only 2200 meters, and a relatively low speed of 250 meters per second. Used carefully, the vehicle's load of 8 missiles can easily knock out 8 enemy tanks!

Additional armament

Some tanks are armed with several guns in one or more turrets. Evaluate the additional weaponry and give advice on its use. Describe the ammunition available for additional weaponry. Give advice on about how to use them and how to fill the ammunition storage. If there is no additional weaponry remove this subsection.

Machine guns

Offensive and anti-aircraft machine guns not only allow you to fight some aircraft but also are effective against lightly armoured vehicles. Evaluate machine guns and give recommendations on its use.

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".

History

Describe the history of the creation and combat usage of the vehicle in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
